Session variables being lost in IE7

has anyone else experienced, heard of, or solved this issue?
I have a web app thats been running fine for 5+ years and using session variables (i'm currently using CF8).
When a user goes from page to page the session is carried with them so i know their login info. However, recently some users (and not all) have complained that after logging in fine (meaning the sessions variables are created) and go to another page off of the main one only to get a timeout issue. I've compared everything from IE settings to server settings, etc. but found no differences. It's like once they navigate to another page in the app the sessions are not carried to the next page.
My timeout code is written so that if the session variables that are created at login are not present the message will show.
Some users had to revert back to IE6 and it worked fine. Is there something they did wrong with ther IE update or is there some sort of server hot fix for this?
Hope someone can help... i'm baffled.

That forum you posted is definitely my issue! However it still is unresolved and the users have yet to pinpoint the cause (just like me). I too firmly believe its due to an IE7 upgrade b/c that is when this happens.
I've checked out the user cookies. I used this script and put it on my server and had the user try it:
http://www.bennadel.com/blog/730-Testing-ColdFusion-Session-Cookie-Acceptance.htm
The cookies are passing over to the next pages fine (this script showed a success on the user machines). But ye the sessions are lost in my app. the CFID and CFTOKEN are changing when the user clicks to go to another page after login.
In fact I have the CF8 server monitor up and running and when someone logs in I can see the their session info under the MEMORY USAGE --> Sessions by memory usage.
I'm finding that users with this issue can log in fine but the session never gets registered with the server?!? Their CFID and CFTOKEN is not showing as an active session and when they click to another page their CFID is always different than their original?
Any thoughts?

Session variables being lost

In my onApplicationStart method (which should tell you I'm
using an Application.cfC, not cfM), I have a cfif loop that passes
a value to a custom tag and returns a form variable. I'm then
reassigning that variable to a session variable. In IE, this works
just fine; in Firefox, though, the session variable is NOT being
set.
What might be causing this, and is there a workaround?

The issue referred to an external CF custom tag, which called
another demo application to set a testing user. However, after
further testing, I realize that demo app won't function properly
with this application, so I've removed it.
Authentication is being set by an LDAP query; this
application that I am working on is going to be a sub-application
of a larger application, and the authenticated user is being set as
a session variable as well (I think...). However, I'm creating a
new session variable for this application, and simply passing the
authenticated user into my app (the outer app uses the variable
auth_user; I'm using the variable authuser, so there is no name
conflict).
Again, it is IE that is not persisting the session. Firefox
is doing so. I have looked in the advanced settings for IE, and
there is nothing about persisting session variables to check or
uncheck. Also, this application will probably be used mostly by
users using IE 6 with default settings, so I'm going to need to
find a workaround for IE.
Your help is most appreciated.

Session variable being lost between parent and include file

I am running into the following scenario: Page 1 includes page 2, on both pages a session variable is returned to the screen. On occasions, page 2 throws an error on the session variable even though it was successfully called on page 1.
It only happens occassionally, and is very difficult to recreate in order to debug it in realtime. Has anyone run into something like this before? Thanks!

I suspect it has less to do with page-inclusion, more to do with the code on page 2. Suppose, instead of using cfinclude, you had copied the code from page 2 into page 1, and made 1 page of it. Then the error would still have occurred. That's at least my theory.
Have a look at how the code in page 2 handles the session. There is bound to be something not quite right about it. What kind of error do you get anyway?
Runtime debugging can be as simple as this:
<cftry>
<cfinclude template="page2.cfm">
<cfcatch type="any">
<cfdump var="#cfcatch#"><cfabort>
</cfcatch>
<cftry>

Coldfusion session variables being lost

ok so when my users login I establish session variables. one of these is employee id. in my Application.cfc I have this at the top:
<cfscript>
this.name = "My App";
this.sessiontimeout=CreateTimeSpan("0", "0", "45", "0");
this.SESSIONMANAGEMENT="YES";
this.SetClientCookies = "true";
this.setDomainCookies = "true";
</cfscript>
i also set the timeout for sessions at 45 in the CFadmin too.
after a successfull login i capture their session.employeenumber by authenticating through our corporate LDAP. no problem there. note: this app has run smoothly for 6+ years now but something has recently gone wrong.
on every page i reference a file in my application directory called "check_session.cfm" like this:
<cfmodule template="/myApp/Tags/check_session.cfm">
In that file I have code that checks for the existence of the session.employee_number. if it doesn't exist they either timed out or book-marked a page in the app in which they need to be logged in to view:
<cflock timeout="30" throwontimeout="Yes" type="READONLY" scope="SESSION">

<CFIF NOT IsDefined("Session.employee_number")>
     <CFLOCATION URL="http://#cgi.HTTP_HOST#/myApp/LoginAgain.cfm">
</CFIF>
</cflock>
every now and then (i'd say on average 5 times per week) i get an error message from a user (i re-direct all errors to my email with diagnostic info). the error reads "Element EMPLOYEE_NUMBER is undefined in SESSION". when i look at the page the error came from i see my call to the check_session.cfm file about 50 lines above where this error happened when i tried to reference session.employee_number. why wouldn't it not find it and re-direct the user to the timeout page? i can never duplicate this error on my machine either... i always get the right result without the error message. its a random, sporadic, intermittent error.

Here is the diagnostic error information. Where you see [omitted] i've changed the URL for the purposes of displaying this detail in a public forum:

Session variable is lost

I have developed a system and it had been used for 6 month
already, it started had problem last week, user can log in system ,
but after they click the each menu tab, the system give message
"please login system" because the session variable is lost.
I tried to debug the file and find that the session.userID is
there in the file where I set it, but it become empty in other
page.
The weird thing is that it did not happen to everyone, most
of user don't have problem, only a few user login and the session
variable is lost after they move from login page to different page,
when I did cfdump to output all session varibale, I found that
seesionid changed from page to page for those user who had problem,
the user who had problem now did not had problem before and I did
not change any code, I tried the internet setting which still did
not fix problem.
I am wondering whether it is related to cold fusion server
setting.
Please give some advice.

Restricting particular session variables being shared

i am using weblogic 10.3.
I have an EAR with has 2 WAR in it , with session sharing enabled in the weblogic-application.xml . I understand that this will make all the variables that are added in the session to be shared by both WAR, but i want a particular variable added in the session not to shared by both WAR, it should be accessible by only WAR1.
Please help me
Zeeshan

"Restricting particular session variables being shared"
You can use the 'transient' keyword for this purpose, for example,
public class Example implements Serializable {
private String replicate;
private transient String notReplicate;
}The 'replicate' attribute is replicated when the Example object is put in the session, the 'notReplicate' attribute is not.

Session Variables Randomly Lost between Pages

My web page uses a session to keep track of who logged in.
What I noticed is that the session variables stored appears and
disappears randomly on different pages. The wierd thing is that my
code is very simple.
For the life of me I can not figure this out....

I go through a hosting company and do not expect them to do
any load balancing.
What are sticky sessions?
The cflocation tag also has the addtoken="yes" to it now and
symptoms persist.
I tested the case with
sessiontimeout=#CreateTimeSpan(0,2,0,0)# instead of the
sessiontimeout=#CreateTimeSpan(0,0,120,0)# and symptoms still
persist.
Any other suggestions? I think I ran into a wall
here....

Session is being lost between GET and POST

My application is being developed in Tomcat 4.1.18.
I have a servlet that acts as a Controller and JSP's that make up the View. Basically, the session gets lost in the following manner:
The application's web.xml file is set with Authentication method of Unspecified. Basically, it's not a high security application, we just need to make sure that the user maintains a session throughout the application.
User is presented with a page (login.jsp). They present their credentials. The controller does an include (RequestDispatcher.include) on a jsp (this jsp simply does a setProperty *) to fill the bean. Then, the controller passes control (through RequestDispatcher.forward) to the Action servlet. The Action does some processing and forwards to the next destination. Next, the user clicks on a link (GET) (this causes the URL to be rewritten with the correct session ID). In this particular instance, the user is presented with a form to fill out. The user fills out the form and it POSTS to the controller. At this point, the controller attempts to access the session and it is lost!
Frustrating. Please feel free to email at [email protected] Thanks.

I just tried encoding the FORM ACTION and no dice. I'm pretty new to JSP's so I'm wondering if its something stupid that I'm doing (or not). I've never had this problem using straight servlets before.
It would be hard for me to justify getting rid of the JSP's and going with a straight servlet solution.
I'm also wondering if my Authentication:Unspecified in the web.xml file has anything to do with my current troubles.

Variable being Lost

When I run the following script, the variable userParty is lost between the scoreCalculate function and the bottom of the script, where it should set the value of the quizVariable.party for the URLloader to function correctly.
//Variables
var userParty;
//Event Listeners
addEventListener(Event.ENTER_FRAME,scoreCalculate);
addEventListener(Event.ENTER_FRAME,partyPicker);
testClip.stop();
//Work Out Which Party the User is Suited for
function scoreCalculate(event:Event) {
    if (theScore<=10) {
        userParty="liberaldemocrat";
        removeEventListener(Event.ENTER_FRAME,scoreCalculate);
        //trace(userParty);
    } else if (theScore <= 20 && theScore > 10) {
        userParty="labour";
        removeEventListener(Event.ENTER_FRAME,scoreCalculate);
        trace(userParty);
    } else if (theScore <= 30 && theScore > 20) {
        userParty="conservative";
        removeEventListener(Event.ENTER_FRAME,scoreCalculate);
        //trace(userParty);
//Send Party to DB
var myURLRequest:URLRequest = new URLRequest(".../major/partyhandler.php");
var quizVariables:URLVariables = new URLVariables();
quizVariables.party = userParty;
myURLRequest.data =quizVariables;
myURLRequest.method = URLRequestMethod.POST;
var loader:URLLoader = new URLLoader();
loader.load(myURLRequest);

Then the same applies for that picker function as well... it doesn't need to be a function either, and both can be combined into one set of conditionals. Probably the most important line added for trying to resolve your problem is shown in red...
trace(theScore); // what does this show?
var userParty;
   if (theScore<=10) {
          userParty="liberaldemocrat";
          liberaldemocrat_clip.play();
    } else if (theScore <= 20 && theScore > 10) {
          userParty="labour";
          labour_clip.play();
    } else if (theScore <= 30 && theScore > 20) {
          userParty="conservative";
          conservative_clip.play();
//Send Party to DB
var myURLRequest:URLRequest = new URLRequest(".../major/partyhandler.php");
var quizVariables:URLVariables = new URLVariables();
quizVariables.party = userParty;
myURLRequest.data =quizVariables;
myURLRequest.method = URLRequestMethod.POST;
var loader:URLLoader = new URLLoader();
loader.load(myURLRequest);

Variable being lost after CONNECT BY...PRIOR query

Im having an issue with the following code (snippet posted):
SELECT ewpm_project_id INTO pro_id FROM ewpm_work_package WHERE
ewpm_work_package_id = wp_id;
--can return pro_id here
SELECT ewpm_work_package_prefix, LEVEL INTO parent_prefix,
parent_level

WHERE ewpm_project_id = temp_pro_id
AND ewpm_work_package_id = wp_id
START WITH ewpm_work_package_id = pack_id
CONNECT BY PRIOR ewpm_work_package_id = ewpm_work_package_parent_id;
RETURN pro_id;
The pro_id value is correctly set during the first select statement, I
can return the pro_id in the commented position. However, I can not
return the value after the second select statement. All I am getting
back is a null value. If I remove the START WITH.. CONNECT BY
clauses in the second query, the pro_id value is returned correcly.
Has anyone experienced this before, or know what could be causing it?

However, I can not
return the value after the second select statement. All I am getting
back is a null value. If I remove the START WITH.. CONNECT BY
clauses in the second query, the pro_id value is returned correcly.How do you use this function ? If you use it in SQL query then any
SQL statement raising NO_DATA_FOUND exception leads to NULL returning
as a result (like the subquery in a selection list which returns no one row):

The session variable has no value definition

Hi Gurus,
For all Dashboard reports and Adhoc reports suddenly we are facing the below error for some users
A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 23006] The session variable, NQ_SESSION.AREA, has no value definition.Please have your System Administrator look at the log for more details on this error. (HY000)
In those dashboard reports we are not using any Area prompts even if we take only area column in analysis also it is showing the same error. But for admin the reports are coming fine only for some users it is showing like that but previously it was fine.
Regards,

Hi,
this means your init block is not working. Check the init block why its not resulting in any data.
only when init block doesn't not result in data , server checks for default value for the variable.
Since there is no default value, you get this error.
Init blocks can fail because
1. connection pool is not working.
2. The table or view does not exist
3. no data in the table
4. filter in the sql in init block is not initialized if its coming from another session variable.
typically no data should bring no results in a report.
Since you have a session variable being part of the report, and that variable failed to initialize you get this error.
Thanks,
Satya Ranki Reddy

Printing a Web Report Using Firefox Results in Lost Session Variables

Post Author: AVXFlyer
CA Forum: .NET
I'm having a problem with Firefox users printing a Crystal Report from a web site.
The first page of the web site collects information to be used in the report generation, for example, start date, end date, type of report etc. These are all various text boxes, drop down lists, radio buttons and check boxes. When the user clicks to show the report, everything works fine and the first page of the report will display. The code behind this page takes care of saving al the session variables into hidden fields on the page so the settings will be accessible when the user clicks to view the next page of the report.
On clicking to view the next page of the report, everything is still fine and the process works beautifully and I've had no problems.
A new problem has surfaced during the printing of these reports. Users who use IE6.0 or IE 7.0 do not have a problem, however, users who use Firefox do have a problem.
It seems that the print dialog which appears as part of the the Crystal web control manages to 'lose" the variables which were present on the calling page. It only does this with the Firefox browser. Calls on postback to retrieve the variables from the hidden fields result in 0's or empty strings ("").
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init .... .... If Me.IsPostBack = False Then ... ... strDiscontinuedOnly = Request.Form.Item("ddlInvStatus") If strDiscontinuedOnly = Nothing Then isDiscontinuedOnly = False Else Select Case strDiscontinuedOnly Case 0 'All Inventory isDiscontinuedOnly = False Case 1 'Discontinued Inventory isDiscontinuedOnly = True Case 2 'Active Inventory isDiscontinuedOnly = False End Select End If Else 'Postback is true intRequestedReport = Request.Form.Item("fldReportID") strDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly") isDiscontinuedOnly = Request.Form.Item("fldInvDiscItemsOnly") ... ... end if

Can't explain it, but here are a few tests;
1) Try to print a saved data report
2) Try to print a report that is not using parameters
3) Try a different printer driver as "default"
4) Enable the option "Dissociate Formatting Page Size and Printer Paper Size" on the report
5) What format do you export to?

Session Variables Not Sticking

We are having issue with Session variables sticking from page to page in our Admin area of our website. You can login, but as soon as you click on another link (or anything) they drop.
It's not a code issue because we have the same code on 2 other networks and it works fine. We also have the same code on our backup website on the same network and it works fine. The backup is on a different server in a different location. So that's 3 networks the code is running fine on. It even worked on this network on the main website up until about 9 months ago. I've verified/reverified the code mutiple times. Something must have happened with security patches, some IIS setting, or other server related issue. We are running 2003 Windows Server Edition SP2 and Coldfusion version 8,0,1,195765.
The browsers used are IE7 and IE8. I don't think it's a browser issue because I can open another tab in the same browser and login and stay logged in on the website on another network. We have already gone into browser advanced settings to make sure session variables are allowed. We've also had a couple of other admins look at it from various locations throughout the Country and they also cannot stay logged in on our main site. They can all stay logged in on the backup site.
Frustrating beyond belief. I'm betting it's a Microsoft issue. Anybody out there have a similar issue or know what it might be?

I've experienced a similar problem with CF8 using IE8. I've narrowed it down to being cookie related which causes CF to loose the existing session and create a new session. For me, I can consistently duplicate the issue by having multiple tabs open to various sites and then accessing my site to login -- login is successful but the first page request is treated as unauthorized because the session is empty. If I shutdown and restart the browser and bring up only my site, everything works fine. And once I'm logged in, I have never lost a session by opening other tabs. And this has never failed using Firefox or Safari. What is very strange is that I have multiple sites using CF8 and CF9 and only one exibits this behaviour.

Using Session Variables for User Login - sometimes they don't persist... what am I doing wrong?

Hi all,
I'm running a site that requires user login. I approached the building of this site as almost a complete newb to CF (and dynamic coding in general), and it's been a great learing experience (with lots of help from you guys).
However, I guess I never learned the correct way to handle a user login. It seemed to me that I could just test the user-entered credentials against those stored in a database, then set a session variable containg that user's record number. Then, not only would I have an easy way of knowing who this user was and therefore what info to serve him, but I could test for the existence of a valid login on every page in the protected folder, by adding this code to my application.cfc in that folder:
<cfset This.Sessionmanagement=true>
<cfset This.Sessiontimeout="#createtimespan(0,8,0,0)#">
   <cfif NOT isDefined ("session.username") or NOT isDefined ("session.password") or NOT isDefined ("session.storeID")>
     <cflocation url="../index.cfm" addtoken="no">
   </cfif>
...and it goes on to run a query and verify that the session.username and session.password match for the store defined by session.storeID. If not, all session variables are cleared and it bounces you back to the login page. When the user clicks Logout, all I do is delete all the session variables.
This seemed to work great for like a year, but lately I've been getting reports that the login doesn't seem to persist for longer than approx. 20 minutes of inactivity. You can see I specified session variables to remain active for 8 hours (I know that seems like a drastically long login, but it's what's necessary for this application). I've only gotten this report from a few people, and I myself can't seem to duplicate it... I've tested an inactive login for 45 minutes now and it held.
SO: any reason you can think of why session variables would be spontaneously clearing for some people? Would having your router reset its IP address invalidate the session or something? Also, the problem seemed to begin appearing after my host upgraded all their servers to CF9... could there be any relation?
And on a more general note... did I go about this completely the wrong way to begin with? If so, what's the standard way to manage a login?
Lots of questions, I know... thanks very much for any answers or suggestions!
Joe

Ian,
Thanks very much - very helpful information.
Sounds like passing the tokens in every request is probably the way to go for this. I don't think it's likely that any users will be sharing links, unless they actually intend for the recipient to see their info anyway.
Is that all I would have to do, is add the tokens to every path? Would that guarantee that all the session variables would remain valid until timeout or being cleared?
Again, thanks, you've been really helpful.
Joe

Unfortunately this is the nature of HTTP web applications. There is NO state maintained from HTTP request to request. This is by design in the HTTP protocol specifications.
ColdFusion provides two methods to circumvent this limitation. Each method has limitations and caveats. They both rely on the passing of tokens between the client and the server with every request. These tokens can be passed as cookies OR URL (GET) variables. You are using the cookie method, which is the simpler and most common. You may be experiencing the limitation of this method. If something happens to the cookies the session can be lost.
You could pass the (CFID & CFTOKEN) OR JESSIONID tokens through the URL query string with every request. This requires one to add these values to every link, form action, cflocation or other request path in our application. ColdFusion provides the session.urltoken variable to make this easier to do. The tokens will be visible to the user. Also if the links with an individual token is share with other users, via e-mail, chat, social networks, etc and one of these users utilize the link during the life of a session (8 hours apparently in your case). Then that user will access the session of the original user.
Cookie session management is by far the most common choice by CF developers. If these methods do not meet your needs you would need to go beyond the HTTP limitations of web applications. One might be able to accomplish this with a Flex|Air|Flash applications that can be configured to use a continuous connection to the server. Thus not suffer the stateless nature of the normal HTTP request-response cycle.
I do not know if a router resetting would cause cookies to be discarded or otherwise invalidated. But I would not think it is beyond the relm of possibilities.

Session variables dropping

I've been having this problem for a long time so I thought
I'd post again and maybe get a hit this time.
We run off windows cfmx 7.x now fully patched, prior to that
we were on cfmx 6.x. We use session management only. Many times on
a new page hit the user loses about half of their session variables
up to all of them. Typically we have them test on the same machine
using different browsers. 99% of the time switching from IE to
firefox solves the problem, most of the users have had IE 6.x.
I experienced this problem myself for about 4 months time and
I could reproduce it daily when neccessary by simply opening a new
window to our application and the session information would persist
to the new window but the parent window would receive a new cfid
and lose all session information. New windows aren't the only
issue, we see a lot of lost session variables in one click, same
window, functionality. I've had hooks in place to test if the
domain was different on page hits removing the www or something but
so far have not found anything there. Each time a new CFID is being
issued and they are losing the original. We attempted to put CFID's
in the URL at all times but that leads to other issues and didn't
solve the problem for us anyhow.
This has been a serious issue for awhile and browsing these
forums I see others are experiencing it to some extent too. I'm
wondiner if anyone has any tips or can confirm the CF Admin/app.cfc
setup you use if you're not seeing any problems like this.

right... response.sendRedirect(). sendRedirect works by sending a repsonse to the browser with a location header. The browser sees that header and makes a new, separate request to the new location. It's no different then typing the location in the location bar in the browser or clicking a link.
But that doesn't matter. If you have 2 web applications (aka 2 servlet contexts) on the server, they are not going to share sessions between them. So the first page is working off one session in one context with some ID. Then the redirect sends it to another page in a different context. That session ID is not valid in that 2nd context, so a new session is created like it was a first time user. And if you redirect back, you may not get the same session for the first context, unless the session ID cookie defines the path as well (I'm not sure offhand).
The "application" object is the servlet context, specifically a javax.servlet.ServletContext object (or implementation of the interface, technically). Nothing is shared between contexts.
Now, you can always share things in one way or another. Store things in a database or in files. Use a messaging system like SOAP or JMS. Maybe the server allows for contexts to access each other (they aren't shared in that case, just that you can get a named context and read what's stored in it).
Or don't have your separate contexts, use subdirectories in the same context.
