RE: Points of failure for session variables
Yes, just reading session.QueryName would be a read. But cfquery name=session.QueryName ... is a write into the session scope. Or at least that's what MM Tech Support told me, and it made sense so I exclusive locked it. Chris Norloff -- Original Message -- from: Daye, Marianne [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] date: Tue, 2 Oct 2001 10:57:31 -0400 Chris, what did you mean when you said that a query with a name of application.queryname is a 'write'. Doesn't that depend on what you do with it? If I loop through session.QueryName, but only read the values, is that not a 'readonly' for locking purposes?

RE: Points of failure for session variables
There is also an issue if you have several servers. Session variables are not really a good use... for it is only being stored on one server and won't be available on the other server.

RE: Points of failure for session variables
Howard, Keep this axiom in mind when developing your application: The Web is Stateless. Each page request is independent and isolated from each other. The only way to maintain state is for the web browser to tell the server who it is. This is done either with cookies, URL variables or form fields. In all cases the web browser is telling the server who it is so that the server can determine what should be done. Cold Fusion uses two tokens to maintain state: CFID and CFTOKEN. They are assigned on the first request and if enabled CF attempts to send them to the browser as cookies. On each subsequent request the browser sends them back. In this way CF can maintain state and allows you to use both Session Variables (stored in memory) or Client Variables (stored in a database). If the browser won't accept cookies then the browser needs to pass those tokens back to the server as a URL variable or as (hidden) form fields. The obvious down side to using URL variables is that someone can have their session hijacked if they send the link to someone else. The link will look something www.somedomain.com/mypage.cfm?CFID=234CFTOKEN=820123 which is someone else's session. It's not a perfect world we Internet gurus work in smile.

RE: Points of failure for session variables
I under stand about statelessness ... As I understand it, there are two types of cookies -- cookies that are written the client's disk and cookies that are session cookies and are stored in the browser (and therefore lost when the browser is closed). My assumption is, in using session variables, you are relying on these session cookies. I wonder how often session cookies are blocked. And if they are blocked, what are the consequences to the application. I'm seeing a lot more cookie blocking on some other sites. So do session variables relying on session cookies? Will session variables work if all cookies are blocked? H.

My assumption is, in using session variables, you are relying on these session cookies. No, by default, the CFID and CFTOKEN cookies created by CF are persistent. Will session variables work if all cookies are blocked? They can work, if the developer is careful to pass CFID and CFTOKEN values from page to page consistently. CF doesn't care how you pass these values from one page to the next - cookies make this easy, but if you can't rely on cookies you can put the values in URL parameters.

What version of ColdFusion are you running, Brian? The SCOPE attribute of the CFLOCK tag was not introduced until (group, correct me if I'm wrong here) ColdFusion version 4.5. If you're running a version earlier than this, you'll need to use named locks instead of scoped locks. You can find out what version of ColdFusion is being run by logging into the ColdFusion Administrator and clicking on the Version Info link in the left-hand navigation menu (or, if you're running ColdFusion 5, it's on the top menu across the page).

A couple of questions that I can't seem to sort out from reading the DOCS... 1. Why would one need to use cflock when WRITING session.variables ? Because users can open multiple browser windows in the same session or if you have a framed environment the session scope really is shared. 2.

RE: CFLOCK and Session variables
You need to use CFLOCK to read and write session variables, the potential problems arise when a person browsing the web double clicks on a link, or someone sends a url out with cfid and cftoken on them. Session variables are shared, because they are accessible to all CF threads. When a person double clicks a link two requests are sent to the web server at nearly the same time, these two requests will likely be processed in different threads, that both have access to the session variable, if both try to write this causes an error. You need to use CFLOCK to read variables because if another thread is writing to a variable and a read request is sent at the same time you will get corrupted data, and possibly crash the server. There is a setting in CF administrator that does automatic read locking for you. I would have though this question would be in the FAQ (http://www.thenetprofits.co.uk/coldfusion/faq/ maybe its there I just looked quickly) I know its been answered several times in the past. +++ Pete Freitag ([EMAIL PROTECTED]) CFDEV.COM ColdFusion Developer Resources http://www.cfdev.com/ -Original Message- From: Gonzo Rock [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 05, 2001 12:45 PM To: CF-Talk Subject: CFLOCK and Session variables A couple of questions that I can't seem to sort out from reading the DOCS... 1.

RE: CFLOCK and Session variables
CFLOCK is very important. ColdFusion is a multi-threaded application. Not locking writes to these variables could result in variable (memory) corruption. You should get into the habit of using CFLock even when simply outputting a applicatio, session variable. Ben Forta's excellent CF5WACK book - http://www.forta.com/books/0789725843/ explains locking in fine detail.

RE: shopping cart--switching to SSL with session variables
The downside is that if someone sees the CFID and CFTOKEN on another box (don't ask me how), they can steal the users session and have access to all information that would normally be available. We had this problem on a site I worked on and had to avoid ever passing the CFTOKEN and CFID around in the query string, even if there wasn't a good chance that someone would steal your session (you can't be too careful!). Also make sure there isn't already a ? in the query string - ColdFusion seems to choke on multiple question marks in the query string sometimes. -Original Message- From: Megan Cytron [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 29, 2001 5:10 PM To: CF-Talk Subject: shopping cart--switching to SSL with session variables Does anyone foresee any problems with appending ?#session.URLToken# to the url to which a form submits when switching from an insecure server to a secure server. It seems to work great in preserving the shopping cart session for this particular project, since everything is on one box (and has enabled us to avoid delving into WDDX or database storage). It essentially helps the secure server to locate the session by passing a CFID and CFTOKEN. Just wondering if there are any downsides to doing this that we may not have considered... Thanks!

accessing Cf session variables on same server from another virtual domain
I have an application which was running on a single domain and I'm porting to multiple virtual domains. These must share a a single secure domain for collecting credit card information. Unfortunately, session variables, which are used throughout the application, are specific to each domain, so the secure session has no access to the session variables, e.g.: session vars on www.thevirtualcompany.com secure session is www.sharedsecuredomain.com Does anyone know of any ways to have the secure session access the session variables from the other domain, both domains of course on the same server?

Yes pass the cfid cftoken in the url, but this will only work if the domains are on the same machine!! And btw is not very secure!!

Set your CFID/CFTOKEN to apply to the entire domain with the SETDOMAINCOOKIES=yes attribute of CFAPPLICATION tag (like you would if you were using load-balancing). I don't think that's going to help the original poster, since SETDOMAINCOOKIES simply allows CFID and CFTOKEN cookies to be shared among multiple hosts within a single domain, not across hosts in separate domains.

You could try writing the variables into a file in a central directory, then read them into your scripts via mapped includes.

RE: CFFILE Output--how do I include CFLOOP and session variables
Hi Megan,
CF Tags will not be interpreted when enclosed in a string variable. Note
that functions will be interpreted as long as they are enclosed in #'s.
i.e.
cfset output = Date: #DateFormat(Now(), mm-dd-)#
This is especially poignant because of CF5's ability to create UDF's. If
you're using CF5, you could write a user-defined function that created and
formatted the content of this file. You probably only do this in one
section of your application, so it's actually a poor example of where to use
UDFs, but you get the point.
Anywho, here's what you're looking to do:
cfscript
//Create a variable to hold a carriage return newline
vCR = Chr(13) Chr(10);
//Create a variable to hold a tab.
vTab = Chr(9);
//initialize your output variable
textoutput = ;
//create the order file header
textoutput = Order: vTab getMaxOrderID.MaxOrderID vCR vCR;
//loop through the contents of the session shopping cart
for(i=0;i=ArrayLen(session.cart);i++){
textoutput = textoutput ITEM CODE: vTab vTab
session.cart[i][3]
vCR;
textoutput = textoutput VARIETY: vTab vTab
session.cart[i][1]
vCR;
textoutput = textoutput QUANTITY: vTab vTab
session.cart[i][4]
vCR;
}
/cfscript
!--- Write the file to disk ---
CFFILE ACTION=Write
FILE=E:\websites\foo.txt
OUTPUT=#textoutput#
IMO,
For readability and flexibility, I would also recommend using an array of
structures instead of a two-dimensional array for your shopping cart.
Something like:
session.cart[1].itemcode = SHOE-09201;
session.cart[1].variety = BROWN;
session.cart[1].quantity = 1;

Subject: CFFILE Output--how do I include CFLOOP and session variables
I'll preface this dodo-brain question by saying that I'm
completely sleep-deprived, half brain-dead and away from my home
base, references, etc.
Here's what I need to do: we are using CFFILE to write the
results of an order to a file. We are using CFSET to create a
variable called textoutput. When I put CFLOOP in textoutput
and then reference it within CFFILE, all of my session variables
(from a shopping cart) get messed up and I get an error message
saying that my session variables are no longer there. (My
shopping cart is working fine elsewhere and I'm able to send the
looped session info via CFMAIL, so that probably isn't the
problem.)
Here's my code:
cfset textoutput=
Order: #getMaxOrderID.MaxOrderID#
CFLOOP INDEX=loopcount From=1 To=#ArrayLen(session.cart)#
ITEM CODE:#session.cart[loopcount][3]#
VARIETY: #session.cart[loopcount][1]#
QUANTITY: #session.cart[loopcount][4]#
/cfloop
CFFILE ACTION=Write
FILE=E:\websites\foo.txt
OUTPUT=#textoutput#
I know I've been down this road before... is it possible to run
CF tags within CFFILE? Am I missing something really simple?
Any insight would be greatly appreciated!
Thanks in advance!!

Re: session variables - newbie
Julie, My first suggestion would be to make sure that you're application.cfm template has the cfapplication tag in it and that all of the attributes are set properly (i.e. sessionmanagement=yes sessiontimeout=#CreateTimeSpan(days, hours, minutes, seconds)#). I would also try a few little debugging techniques like cfoutputing that session variable in one file at a time to see where it loses it. I generally put it as the very first thing inside the body tag and outside any tables. That way, when you run the page, you should see the value displayed somewhere at the top of the page. This will help you isolate the problem. Hope this helps, and welcome to cf.

Rob, I have experienced a similar problem on IE5 for the Mac - it just seems to refuse to store the CFID and CFTOKEN variables as cookies unless you turn don't specify the expires attributes of the cookie. ie, like this cfapplication name=RugbyScene sessionmanagement=Yes setclientcookies=No cfcookie name=CFID value=#CFID# cfcookie name=CFTOKEN value=#CFTOKEN# (Can't remember exactly where you get the values for CFID and CFTOKEN - I think they are just local variables - you will have to check. Otherwise you might need to set: CFSET CFID = Session.CFID CFSET CFTOCKEN = Session.CFTOCKEN) Donno if that will help you - not having the variables persistant didn't help me :( Regards David -Original Message- From: Rob McLennan [mailto:[EMAIL PROTECTED]] Sent: 05 July 2001 08:17 To: CF-Talk Subject: Lost Session variables I have a an end user using IE5 on Windows ME who is unable to maintaing her session variables.

Re: Cookies vs. Session Variables
switch to session vars, and pass the urltoken on every request and set the setclientcookies attributes to no in the cfapplication tag. this last bit is to prevent cf from correlating requests into a session via a cookie on the user's machine. cflocation will pass the urltoken automatically if you don't say addtoken=no, but on your forms and links you will need to add #urltoken# to the end.

RE: Cookies vs. Session Variables
Nope. As a matter of fact, the way CF recognizes the session is through cookies. Run this code to confirm: cfloop collection=#cookie# item=myVar cfoutputCOOKIE.#myVar#/tdtd style=font: 12pt Courier New#evaluate(COOKIE. #myvar#)#/cfoutput /cfloop You'll notice a CFID and a CFTOKEN cookie variable. These values is what CF uses to assert who the session is. You're best bet may be to use client variables, or to create a log off button that clears sessions/cookies. I don't recommend using client variables because they sit in the url, and can be easily hijacked, posing an even bigger security threat. -Original Message- From: Pete Miller [mailto:[EMAIL PROTECTED]] Sent: Monday, July 02, 2001 12:55 PM To: CF-Talk Subject: Cookies vs. Session Variables We have an application that uses cookies to track the identity of a user after logging in.

RE: Cookies vs. Session Variables
Cookies can be set to expire when the browser is closed. AFAIK, you can't overcome this with browser configuration. Sounds like a change in a few lines of your code will fix your problem. Using CFCOOKIE without specifying a timeout will cause the cookie to vanish when the browser is closed and your problem should go away. -Cameron Cameron Childress elliptIQ Inc. p.770.460.7277.232 f.770.460.0963 -- http://www.neighborware.com America's Leading Community Network Software -Original Message- From: Pete Miller [mailto:[EMAIL PROTECTED]] Sent: Monday, July 02, 2001 3:55 PM To: CF-Talk Subject: Cookies vs. Session Variables We have an application that uses cookies to track the identity of a user after logging in.

Re: Cookies vs. Session Variables

Re: Cookies vs. Session Variables
I've never heard of a lab setup like this, but certainly don't doubt it. Is there some reasoning behind the configuration? Session variables, by default, use cookies to maintain identity. You can disable this by using the SetClientCookies=No in the CFAPPLICATION tag. If you do this, you'll have to be VERY careful to pass the CFID and CFToken (two elements to identify every user) in every single URL and Form. If you forget a link someplace, a new session will be started when the user clicks the link. I believe there are examples of this type of setup in Ben Forta's books. This is also the approach to take when working with users that have cookies disabled, as their sessions will die after every page request, since the cookie deletes itself.

Re: Cookies vs. Session Variables
You are correct, cookies should not be used to identify users at public terminals. Most public terminals either disallow persistent cookies, disallow all cookies or reset cookies after use (more common in labs). Sharing cookies is a new one for me, but the problem is the same. The answer is to use logins and session management. At 12:54 PM 7/2/2001 -0700, you wrote: We have an application that uses cookies to track the identity of a user after logging in.

Problems with CFLOCK and session variables?

Exclusively lock all of your sets, and ReadOnly lock all of your reads (references). Just do it, it's not too tough. :) Watch out for application variables too.

Session variables
I would like to figure out the deep dark implementation details of cold fusion sessions. Is there any way I can back into it? i.e. Can you reference a session variable as a hidden application variable? I am trying to do something to an Application variable, based upon the expiration of a session variable. If I knew the inner workings of session variables, I might be able to do this.

Session Variables
Ben or anyone --
I have recently brought Ben Forta's book on ColdFusion Web Application
Development. I need some help on setting ColdFusion variables in
ColdFusion.
I have a login form that posts to a welcome.cfm page and a database. When
the
welcome.cfm page comes up after correctly entering the password and
username,
it says Welcome #FirstName#...question...If someone accesses the welcome.cfm
page directly, there is an error msg that says Form.UserName not available
or whatever,
I want the welcome.cfm page to default to the form automatically when
accessed
directly. And when the form is used, the name to come up from the
database -- I am
having a bit of a problem with this -- I know it has something to do with
session variables
Questions:
1) What should I add to the application.cfm page? I tried this, but now
the firstname doesn't come up...

CFAPPLICATION name="dautolink" clientmanagement="Yes" setclientcookies="No"
sessionmanagement="Yes" sessiontimeout="#CreateTimeSpan(0, 0, 30, 0)#"
applicationtimeout="#CreateTimeSpan(1, 0, 0, 0)#"
2) Here is the login form...(where should I put the cfset code (and what
exactly should
it be to define the session variable of UserName -- should I do Password
also?) - login code below questions.
3) On the welcome.cfm page, where should I put the url relocation code that
uses the session variable, I have
a sample but it didn't exactly work...(directly below)

RE: Session Variables
Julia,
If you want to save a FORM field to a SESSION variable, then (assuming you
have session state management turned on) all you need to do is:
CFLOCK SCOPE="session" TYPE="exclusive" TIMEOUT="30"
CFSET SESSION.FirstName=FORM.FirstName
/CFLOCK
Then you can refer to #SESSION.FirstName# as needed.
Hope this helps.

Session variables stored in SQL server
Hello all, I am wondering if anyone has had any experience with this: I am running a IIS5.0 and CF cluster of 5 servers and one databaser server (sql70) will upgrade to sql2k soon. I was adviced by Allaire to move my session variables to the database, rather than storing them in each server's registry. My question is: How safe is this in terms of client variables getting mixed, or users taking other each other's session variables becuase they would be extracted from one pool, rather than 5? Is there a performance change by moving these variables to a remote database? good?, bad? Any thoughts or ideas on the subject will be greatly appreciated. Thank you!

RE: Session variables stored in SQL server
You're talking about client variables, not session variables. However: They are as safe as they were in the registry as they are keyed on the CFID/CFTOKEN pair which are generated by CF. Make sure in your CFAPPLICATION... you have UseDomainCookes set to TRUE so that no matter which server you happen to being serviced by, the cookies that were set by one machine will be available to one of the others in the farm. Performance-wise, your system will thank you for moving to a RDBMS in the long run as the registry isn't the most efficient of databases and that's basically what you're using it for by storing client variables in there. After a while the registry fills up and system performance degrades - a bad bad thing!

RE: Session variables stored in SQL server
Ok, client vs. session variables 101. Session variables are stored in RAM on the CF server which is all fine and dandy until you create a load-balanced cluster. In a cluster the load-balancing equipment can switch a session to a less busy server at any time - thereby losing a clients session variables (not good). Client variables, however, can be stored in the database (or registry or cookies) and therefore are not server dependant (well, the registry is server dependant). Here's a few points to remember that tripped me up when I first started using them: 1. When declaring CFAPPLICATION you can choose to turn cookies off in which case maintaining state is completely reliant on having the CFID and CFTOKEN in the URL string (unless you set the cookies yourself). This can get messy occasionally if a user bookmarks a page and then comes back later to find that their information has not been deleted (this could be a good thing). 2. When using cookies to hold CFID and CFTOKEN you must replace the default cookies with temporary ones if you wish the client's session to end when they close the browser. 3. If you are using cookies instead of the DB to store client variable information you are limited to 4k characters maximum. The same is true for DB stored client variables if you are using ORACLE. 4. The minimum timeout for a client variable (system defined) is one day. I've been using client variables successfully for quite some time. They are slightly more difficult to understand and manipulate, but they are reliable, scalable, and safe (no CFLOCKS). You would be wise to learn how to utilize them yourself :) Bryan Love ACP Internet Application Developer [EMAIL PROTECTED] -Original Message- From: Andres Leon [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 22, 2001 8:57 AM To: CF-Talk Subject: Session variables stored in SQL server Hello all, I am wondering if anyone has had any experience with this: I am running a IIS5.0 and CF cluster of 5 servers and one databaser server (sql70) will upgrade to sql2k soon.

Session Variables
I'm new at CF. I'm very experienced in ASP however. I am now working on
one of my first CF projects and I'm having trouble with session variables.
In ASP I'm used to having the sessions expire when I shut down a browser.
However, I'm declaring a session variable in cold fusion and when I close
the browser and open the page up again in a new browser, the session
variable is still active. How can I get the session variable to expire when
I close the browser? If this can't be done, is there a way to clear all
session variables the first time the application.cfm is run, but not every
time?

Yvette!
I think you need to assign the startweek to the next
week as you go along as you did, but an idea that
maybe causing the problem is that you may be resetting
the variable STARTWEEK to the current date each time.
Make sure you have that cfset at the beginning, and
make sure that the code doesn't run through it each
time you press the next button.
I hope this help

| Hi:
|
| I'm building a scheduler that only shows a week at a glance
|(horizontally)
| and time slots (vertically). When a user presses the Next

| only get it to go to the next week and no further. Same
|thing with the
| Previous button. Here's some code snipplets. My brain is
|fried at the
| moment. Any help on this is greatly appreciated.

RE: Session variables
The application will run under the MOST RECENTLY declared CFAPPLICATION tag. If you use a second CFAPPLICATION tag in the same call the server will run under that one. There are easier ways to clear the session scope, however. 1. Use the structClear() function - if you do this be sure to store session.sessionID in a local variable and reassign it after the call - i.e. [use cflock here] temp = session.sessionID; foo = structClear(session); session.sessionID = temp; [end lock] 2. You can identify the session variables you wish to delete - [lock] foo = structDelete(session,"key"); [end lock] Actually, I've found that it is easier to create and maintain applications if you can rely on certain variables ALWAYS being around and just test their contents. In other words, instead of deleting the variable, just set it to blank or to zero and check for that in the if statement. That way you can param them to blank or whatever in application.cfm and not bite your nails off trying to figure out why it exists when it shouldn't (or vice versa).

RE: Session variables
Not necesarily. I ran a regression test where I used different locking methods to read 10,000 application variables (same locking issue as session variables) and the results were somewhat surprising; using one CFLOCK tag outside the loop it took 450 ms while using 10,000 individual locks inside the loop took only 600 ms. I performed this experience using CF Server 4.5 on my laptop (Pentium 3 with 256 RAM). As you can see, the effect of one lock or even of 20 simultaneous locks is practically nill. In general I don't use Session variables at all: their multi-threaded nature combined with their inability to support clustering make them dangerous in high-end applications. Despite their seductive nature they are a crutch to beginning and experienced developers alike. Client variables require a little more experience and understanding to manipulate but they do not require locks and can be used in a clustered environment. When used in conjuction with request variables you can successfully create a solid, single-threaded-by-nature application that will scale across as many servers as you want. Good luck!

ANS: What are client and session variables?
This is for the person who asked the question about client and session variables (and of course all you others who want to know...). And before you ask, "yes", it's in the ColdFusion FAQ I'm building. Before we talk about client and session variables, we need to briefly discuss the HTTP protocol and cookies. That will help clarify how ColdFusion tracks users. The HTTP protocol consists of a request-response pair. When a browser requests a webpage from a server, the server's response is to find the webpage on its hard drive and then send the file back to the browser. When the browser parses (reads) the webpage and finds there are references to 5 images, it then makes 5 subsequent requests to the server, one for each image. Those 5 requests are then fulfilled by the server finding the images on its hard drive and sending them back to the browser. The browser then uses the 6 files to display the webpage on the monitor. All of this happens very quickly and helps to hide the fact that displaying one webpage can be the result of a large number of HTTP request-response pairs. Each request that a browser makes to a server is said to be "stateless". That is to say, the server doesn't track a series of requests from a particular browser. Each request is independent of every other request. As long as the server has the IP address of the computer making each individual request, it has sufficient information to send the necessary file (resource) on its way. Certain websites, however, have a requirement to track users - sites with shopping baskets, for example. If the information about the products in a user's basket is stored on the server, that server needs to somehow track users to ensure that baskets don't get lost or mixed up. How, then, do we address the fundamental statelessness of the HTTP protocol? The answer is with cookies and a pair of values called CFID and CFTOKEN. A cookie is the name given to a simple string of text. Firstly, let's clear up how cookies work. Setting a cookie in a browser works as follows. The browser requests a file from a server. The server's response is to send back the file, along with a command to "set" a cookie in the browser. If the browser is configured to accept cookies, the cookie is said to be "set". Every time the browser makes a subsequent request from the same server, the cookie is returned to the server along with each request. For example, if we set a cookie in a browser that had a value NAME equal to FRED, every time the browser asked for another file from the same server, along with the request would come the information that NAME=FRED. If there were several browsers all making requests from one server, so long as they are all returning different NAMEs, we could use the cookie's NAME value to identify which browser each request had come from. ColdFusion utilises this behaviour to first differentiate and then track users. However, instead of using a cookie with a value called NAME, it uses two values called CFID and CFTOKEN. The first time a browser makes a request for a page from a ColdFusion server, ColdFusion creates a new CFID-CFTOKEN pair. CFID is an incremental number and CFTOKEN is a random 8 digit number. If the last CFID-CFTOKEN pair created was 100-12345678, the next pair might be 101-87654321. Taken together, each CFID-CFTOKEN pair is unique. When ColdFusion sends the first page back to the browser, it also attempts to set a cookie that contains our newly created CFID-CFTOKEN values. If the cookie is successfully set, every subsequent request from that browser will be accompanied by the cookie containing CFID=101*CFTOKEN=87654321. As long as ColdFusion then receives the CFID and CFTOKEN values along with every request (which is how cookies are designed to operate), it can differentiate requests from different browsers. Client variables are values stored on the server and associated with a particular browser. They are typically stored in the server's registry (a part of Windows where values are stored). Client variables are designed to track users over a long period of time. If a user visited a site and was asked to enter their name in an online form, and this code was on the following page CFSET client.Name = form.Name whatever they typed in the Name form field would then be stored in the registry as a client variable called "Name". Along with Name would be the CFID-CFTOKEN pair of the browser with which they are associated. The user then left our site and didn't return for several weeks. When they did return, the first time they request a page from the server, the CFID-CFTOKEN pair were also sent. ColdFusion sees that along with the request for a page is a value for CFID and CFTOKEN. If then looks to see if the CFID-CFTOKEN pair it has been sent with the request match any of the pairs stored in the registry. It does! And along with the CFID-CFTOKEN value in the registry is another val
Session Variables and password protected folders...
Anyone familiar with session variables not being able to be used through password protected folders? I have a site that works fine on the dev server but won't set session variables on our live site. The site is hidden behind a password protected folder. I checked the settings in the admin and all looks fine to me... and yes, the application.cfm file was transfered over and is being used on each page: cfapplication name="name" clientmanagement="yes" sessionmanagement="yes" sessiontimeout="#CreateTimeSpan(0,0,20,0)#" Any ideas why it may not be working?

RE: understanding session variables
Please explain to me what occurs when you use session variables. The default is for a cookie to me created which stores the cftoken and cfid, correct? What happens when the "cookie" is stored in the registry? Where can I look up what is stored in my registry? And do the values permanently stay in the registry, or do they get deleted when the browser is closed. Oh boy... this is a *big* Q / A I'm rewriting in the FAQ.

RE: session variables
Hi John,
What it might be...
Are you switching domains on the live server using cflocation at any time?
If so, any session/application/etc variables may not be set correctly, as CF
needs to set a cookie with CFID/CFTOKEN to identify the client machine, and
cflocate prevents the cookie from being set
This would explain why your not having a problem on the development server,
as:
1/ The cookie will have already been set
2/ Both sections will be under the same domain
HTH
Dan.

RE: session variables
Ok Dan!
Yes the webserver is on another Domain, but that does not explain why my own
machine can still login to the site.
I tested the session state by outputting the variable and it is defined.
On any other client the session is never defined.
Can you recommend a solution round the domain problem.
Thanks Dan.

understanding session variables
Please explain to me what occurs when you use session variables. The default is for a cookie to me created which stores the cftoken and cfid, correct? What happens when the "cookie" is stored in the registry? Where can I look up what is stored in my registry? And do the values permanently stay in the registry, or do they get deleted when the browser is closed. thanks, eric ~~ Structure your ColdFusion code with Fusebox.

RE: session variables
Check that cookies is switched on:-)
Also is this a farm of computers in a load balance environment:-)
There are ways to do the same thing, without using session variables:-)

Ok Dan!
Yes the webserver is on another Domain, but that does not explain why my own
machine can still login to the site.
I tested the session state by outputting the variable and it is defined.
On any other client the session is never defined.
Can you recommend a solution round the domain problem.
Thanks Dan.

Hi John,
What it might be...
Are you switching domains on the live server using cflocation at any time?
If so, any session/application/etc variables may not be set correctly, as CF
needs to set a cookie with CFID/CFTOKEN to identify the client machine, and
cflocate prevents the cookie from being set
This would explain why your not having a problem on the development server,
as:
1/ The cookie will have already been set
2/ Both sections will be under the same domain
HTH
Dan.

Subject: session variables
Has anyone ever experienced session variables not getting set.
I have created a login page like so,
cfif isdefined("form.uid") and isdefined("form.pwd")
cfquery name="checkLoginUser"
datasource="#application.dsn#" username="sa" password="ruler"
SELECTuid, pwd
FROM dbo.Users
WHERE (uid = '#form.uid#') and (pwd = '#form.pwd#')
/cfquery
cfif checkLoginUser.recordcount eq 1
cflock scope="session" type="EXCLUSIVE"
timeout="30"
cfset session.checkLoginUser = 1
cfset session.LoginUser =
#checkLoginUser.uid#
/cflock
cflocation
url="#application.secureVirtualRoot#admin/control.cfm" addtoken="No"
cfelse
cflock scope="session" type="exclusive"
timeout="30"
cfset session.checkLoginUser = 0
/cflock
trtd bgcolor="#ebebeb" class="main"nbsp;font
color="#ff0033"Sorry!/font but your blogin/b details nbsp;are
bincorrect/b please check!/td/tr
/cfif
/cfif
My application file is between the directories in a directory named secure,
and is like so
cfinclude template="../../application.cfm"
cfif isdefined("session.checkLoginUser")
cfif session.checkLoginUser neq 1
cflocation
url="#Application.virtualRoot#coolcross/index.cfm" addtoken="No"
/cfif
cfelse
cflocation addtoken="No"
url="#Application.virtualRoot#coolcross/index.cfm"
/cfif
When I login through my own client its successfull, the session variable is
set.
If I login on the webserver it is also successful.
If I login on any other client the session never gets set.
