RE: deleting session variables when browser is closed
session variables are automatically deleted when the browser is closed. That is their nature. No, they're not. The server doesn't know when the browser is closed. It only knows that some period has passed since the last request from that browser. Also, by default, the cookies created by CF are persistent, so if you open your browser, go to a site that issues CFID and CFTOKEN cookies, run some code that manipulates your session data, close your browser and then reopen it right away, your session data will be intact. If you want to disconnect a browser from the session data before the session times out, you have to ensure that the cookies aren't returned by that browser. Typically, you do this by creating session cookies, which are nonpersistent. You can do this with the CFCOOKIE tag by omitting the EXPIRES attribute: !--- all of this goes in Application.cfm --- cfapplication name=foo setclientcookies=false sessionmanagement=true .. cfif not IsDefined(Cookie.CFID) cflock scope=Session type=readonly ... cfcookie name=CFID value=#Session.CFID# cfcookie name=CFTOKEN value=#Session.CFTOKEN# /cflock /cfif Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ voice: (202) 797-5496 fax: (202) 797-5444 __ This list and all House of Fusion resources hosted by CFHosting.com.

RE: deleting session variables when browser is closed
Bryan, you're taking a beating today ;D Your post isn't correct, as was pointed out by another user. Run this sample code in its own folder, creating application.cfm and index.cfm. To test this properly you must set client management to Yes, run the file and close the browser *immediately*. Then set client mgmt off and comment out the cookie stuff. This will flush out cfid and cftoken from your 127.0.0.1 cookie and kill cf server's ability to figure out who you are. Your example would work on a dev server whose 127.0.0.1 cfid and cftoken cookies are long-since instantiated regardless of whether or not you enable client management on your current app. Once you flush the cookies you'll see that state isn't maintained unless you use the second link in the example file. --- Matt Robertson[EMAIL PROTECTED] MSB Designs, Inc., www.mysecretbase.com --- CFAPPLICATION NAME=MYTEST_X SESSIONMANAGEMENT=yes CLIENTMANAGEMENT=no SETCLIENTCOOKIES=No !--- cfcookie name=CFID value=#cookie.cfid# cfcookie name=CFTOKEN value=#cookie.cftoken# --- CFIF isdefined (url.action) CFLOCK SCOPE=SESSION TYPE=EXCLUSIVE TIMEOUT=10 CFSET session.myvar=SESSION VAR INSTANTIATED /CFLOCK /CFIF htmlheadtitle/title/headbody click this A HREF=index.cfmlink/AP CFOUTPUT CFLOCK SCOPE=SESSION TYPE=READONLY TIMEOUT=10 Now click A HREF=index.cfm?CFID=#session.cfid#cftoken=#session.cftoken#this one/AP #session.CFID# and #session.cftoken#P Click A HREF=index.cfm?action=1here/A to set a session variableP CFIF isdefined (session.myvar) #session.myvar# /CFIF /CFLOCK /CFOUTPUT /body/html -- Original Message -- from: Bryan Love [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] date: Wed, 20 Mar 2002 14:18:48 -0800 Very well then.

RE: RE: deleting session variables when browser is closed
Partly true on closer inspection. You are correct in that you must pass the variables through the url string - I was mistaken in thinking that the session would persist without doing that. The cfid and cftoken are stored in the session struct however (but I don't know what they are doing there...).

If setClientCookies is set to YES then put this just below the CFAPPLICATION tag: cfcookie name=CFID value=#cookie.cfid# cfcookie name=CFTOKEN value=#cookie.cftoken# Unfortunately, it's not as simple as that. For Session variables to work, they have to be stored in memory on the CF Server, along with the CFID and CFTOKEN identifiers, and the browser has to send those identifiers back to the server on each subsequent request. So, if you set SETCLIENTCOOKIES to no or false, you'll have to ensure that CFID and CFTOKEN get returned via URL or form variables. Also, on the server, there's no way to tell when the browser has closed. All the server can do is tell that the browser hasn't requested a page since some specific time. So, no matter what you do, in a regular HTML-based interface, the Session variables will persist for some time after the browser has been closed. The best you can usually do is to disconnect the browser from those variables, by not storing the CFID and CFTOKEN values as persistent cookies.

We do have one reason for not using session vars.
Clustering.
It takes out the need to worry about the variables being held in memory.

RE: deleting session variables
I am using this code to delete my session variables when a
user closes their browser:
cfif IsDefined("Cookie.CFID") AND IsDefined("Cookie.CFTOKEN")
cfset cfid_local = Cookie.CFID
cfset cftoken_local = Cookie.CFTOKEN
cfcookie name="CFID" value="#cfid_local#"
cfcookie name="CFTOKEN" value="#cftoken_local#"
/cfif
The only problem is that it also deletes my client variables
upon closing the browser. Is there any way to just delete session
variables and leave the client intact??
Actually, this code doesn't delete Session or Client variables.
What it does delete is the link between an individual browser and the
variables on the server. Client and Session variables are associated with a
specific browser via those two cookies (assuming you're using cookies
instead of URL parameters, as you are).
As a result, you can't destroy the link to one without destroying the link
to the other. You could, however, work around this by doing your own state
management - set your own cookie on the browser, then retrieve data based on
the value of that cookie.
A better question for you, though, might be why you're using both Session
and Client variables - two ways of doing the same thing? That's probably not
the best approach.

Rob,
Seems to me that if you do it this way, your not only
expiring the session var's for the intended user, but also
for everybody else using that "application" at that time.
Just expire the session in Application.cfm:
cfif isdefined("logout")
cfapplication
name="myapp"
sessionmanagement="yes"
sessiontimeout=#createtimespan(0,0,0,0)#
cfelse
cfapplication
name="myapp"
sessionmanagement="yes"
sessiontimeout=#createtimespan(0,2,0,0)#
/cfif
Pass the parameter "logout" to any page and the
session will die. You could
also set cookie.cfid and cookie.cftoken to 0 and
expire them too.
Anybody else with any thoughts on the matter?

Just expire the session in Application.cfm:
cfif isdefined("logout")
cfapplication

sessionmanagement="yes"
sessiontimeout=#createtimespan(0,0,0,0)#
cfelse
cfapplication

Pass the parameter "logout" to any page and the session will die. You could
also set cookie.cfid and cookie.cftoken to 0 and expire them too.

RE: Deleting Session Variables
Rob,
Seems to me that if you do it this way, your not only
expiring the session var's for the intended user, but also
for everybody else using that "application" at that time.
Just expire the session in Application.cfm:
cfif isdefined("logout")
cfapplication
name="myapp"
sessionmanagement="yes"
sessiontimeout=#createtimespan(0,0,0,0)#
cfelse
cfapplication
name="myapp"
sessionmanagement="yes"
sessiontimeout=#createtimespan(0,2,0,0)#
/cfif
Pass the parameter "logout" to any page and the
session will die. You could
also set cookie.cfid and cookie.cftoken to 0 and
expire them too.
Anybody else with any thoughts on the matter?

Re: Deleting Session Variables
Try this... This is what I use to kill all session variables. Works perfectly for logout: CFSCRIPTStructClear(Session);/CFSCRIPT CFCOOKIE NAME="CFID" VALUE="0" EXPIRES="NOW" CFCOOKIE NAME="CFTOKEN" VALUE="0" EXPIRES="NOW" Danny Davis - Original Message - From: "Scott Wolf" [EMAIL PROTECTED] To: "CF-Talk" [EMAIL PROTECTED] Sent: Monday, November 20, 2000 2:13 AM Subject: RE: Deleting Session Variables Will arraydelete kill all of the session vars for just that one session? I'm trying to write a logoff page that completely ends a session, and I just want to make sure that I can scrap all the vars without affecting any other user's session. Scott Wolf -Original Message- From: Scott M. Berry [mailto:[EMAIL PROTECTED]] Sent: Monday, November 20, 2000 2:13 AM To: CF-Talk Subject: Re: Deleting Session Variables Session variables are stored in an array. You can kill the array (arraydelete()) but that will kill all the vars and Allaire does not recommend that. You can probably do some nifty functions by converting the array to a list, and finding out the position of the var you want to delete and then doing a arraydeleteat() for that var.. not sure.. guessing here.

How can I remove a session variable completely? I know I can change the value using CFSET (i.e. CFSET Session.LoggedIn = "1") but I don't know how to remove it altogether. Please let me know if you can. Thanks! Scott Wolf ~~ Structure your ColdFusion code with Fusebox.
