Re: Client & Session variables?
Well, there are cookies. They're in the browser only, and not set on the user's machine. So they can maintain state in a session, but not be useful from one session to another. best, paul At 08:56 PM 9/30/00 -0400, you wrote: >On 9/30/00, paul smith penned: > >"Accept only cookies that get sent back to the originating server" > > > >Then state is maintained from one click to the next (and I assume no cookie > >is set on the users machine). > >Really?

Re: Client & Session variables?
Right. New cfid/cftoken every click (in IE). However, if the user selects the following in Netscrape: "Accept only cookies that get sent back to the originating server" Then state is maintained from one click to the next (and I assume no cookie is set on the users machine). best, paul At 05:46 PM 9/30/00 -0400, you wrote: >If they don't have cookies enabled, then I believe a new cfid and >cftoken will be created on every click since CF won't know that it's >the same person clicking.

So to summarize, as long as they have cookies enabled and come back before the client variables are deleted from the database, then yes, your method will work. If they don't have cookies enabled or come back after the data is purged, it won't. -- Bud Schneehagen - Tropical Web Creations _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ ColdFusion Solutions / eCommerce Development [EMAIL PROTECTED] http://www.twcreations.com/ 954.721.3452 -- Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.

The problem with this, client variables can be set to be purged from
the database after a set period, so unless you have your own server,
you're at the mercy of the host. I believe the default is 10 days. I
have my server set to expunge after one day because that's all I need
for any app on my server. Now if someone requested I keep them
longer, I may give them a week, but not much more than that because
then the database just gets larger and larger. And I don't think
there's any guarantee that the person will have the same cfid and
cftoken generated by their browser (still a little confused by that
one) if they've shut it down and come back a few days later.
I use cookies. Then they can click a checkbox if they want their
password to be stored. Then you check like this (just an example from
one of my apps):
SELECT Cust_ID,Cust_FirstName
FROM Customers
WHERE Cust_ID = '#variables.member_id#' and password =
'#variables.member_password#'
Welcome Back #Get_Id.Cust_FirstName#!
Login Failed
Show Login Form
Then as long as client.mem_id is not "" then they are logged in.

Re: [Re: Client & Session variables?]
Good articles. But it's almost the same as the one in Cold Fusion Journal. I'm not sure which one was written first. Also, some of the query will not work in this article. For instance, those ideas about checking client.LastVisit are wrong. Also, you need to do something to the User on the login page. Otherwise those two tables in CVR DB are wrong.

Re: Client & Session variables?
I just noticed the URLed article contains the following: Personally, I require cookies on all of my sites, and I then provide adequate security and cookie information to the users who are refusing or unable to accept cookies so they know why we require them. I prefer setting CFID and CFTOKEN to a "session-only" cookie so that the session is destroyed when the user closes their browser: I then detect whether the user is able/willing to accept cookies, and redirect them to an information page if they are not, using some permutation of: === I did some testing recently, and found if the browser was set to NOT accept cookies, that the above session-only/browser-only cookies were accepted.

Re: Client & Session variables?
Thanks for that Paul. Now as a complete beginner with Session Management (never had to use it). I've followed instructions on the site below, and it's working fine afaik. But how about implementing it straight into a site? For example on one of my sites I have a Members section which they can personalise - they login in using their username and password... So if the user and pass is OK, the rest of the page is displayed. What I'd like to do is after successful validation, use client vars in a DB so that they will be logged in automatically next time.

What kind of documentation? CF will create the necessary tables if
you just give it an empty database. The tables and columns it creates
are, in Access, I can't remember off the top of my head what the
matching data types are in SQL:
CDATA
cfid (text, 20 characters, no index)
app (text, 64 characters, indexed, duplicates OK)
data (memo)
CGLOBAL
cfid (text, 20 characters, indexed, duplicates OK)
data (memo)
lvisit (date/time, indexed, duplicates OK)
The biggest difference in the setup is, if you have complex objects
other than simple strings you have to serialize them into WDDX
packets. Then deserialize them into a local variable.
I do it like this:
To create the initial variable if it hasn't been created (my shopping
cart for example, this will probably wrap bad):
Then when adding something to the basket, whereas with sessions I
would just create a new basket called newbasket then set that to
session.basket, it's a tad more complex:
But well worth it. Clustered server ready and NO CFLOCKS! YIPEEE!
Then I can just cfoutput or loop on variables.basket and access the
different items with variables.basket.product_id, etc. instead of
session.basket.etc
Oh, and if you want to give it a timeout, you can't just do it like
sessiontimeout=. You have to create a start time, then update it at
every click and delete the client variables if it's past the allotted
timeout (30 minutes in the example below). I do it like this:

RE: Client & Session variables?
Definitely! We are setting up a CoyotePoint Equalizer to balance the load between the servers and we are being very careful to keep everything about the user's session in database-stored Client variables.

RE: Client & Session variables?
WEll if you don't kill the sessions though and come back, you keep your session. I think the difference is client variables use a database whereas session variables use memory.

Re: RE: Client & Session variables?
More or less, but session variable can hold after you immediately exit a browser, here is better description: Session: Is stored in memory, and while faster is extremely volatile 'cuz if the server shuts down, all the variables go Client: Stored in registry (whether database, NT, or otherwise) and while slower, is less volatile 'cuz they're on the hard disk. If server shuts down, variables will be there when server comes back up. Just remember this when coding your application.

Re: Client & Session variables?
On 9/29/00, Rif Kiamil penned: >Dear All, What is the different between Client & Session variables? > >From Rif Dear Rif. They pretty much accomplish the same thing. Client variables are unique to each client, may be stored in cookies (if they are turned on), the registry (bad bad idea), or a database (best method). They will persist across sessions (if the server reboots, you don't lose the stuff in your shopping cart, etc.) and across servers in a clustered environment. Session variables are the same thing, unique to each client, but are stored in RAM. No good across servers or if the server crashes. There is a whole cflock debacle with session and application variables (which are similar to session variables in the way they are stored, but are available to everyone using the application). I still haven't figured that one out, so the easiest thing for me was to swear off session variables for good. The upside is, now everything I build will work in a clustered environment. Use client variables, written to a database, whenever possible. -- Bud Schneehagen - Tropical Web Creations _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ ColdFusion Solutions / eCommerce Development [EMAIL PROTECTED] http://www.twcreations.com/ 954.721.3452 -- Archives: http://www.mail-archive.com/cf-talk@houseoffusion.com/ To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
