This question is related to VSTS and above parameters in the request. Question is:
A script created with VSTS for testers has hard coded values for ReportSession and ControlID in the requests, These IDs are expired after some time and scripts fails to run after few hours. Can some one tell me how to set the session expiration time on these ID's in the Report server so I can increase the value to 60*24*365 (1 year) this would solve my problem with hard coded values in the scripts for above mentioned IDs.
You cannot set this stuff for only some sessions -- it's a global property (<SessionTimeOut> in rsreportserver.config) that will apply to all sessions. Setting this to 1 year would be a very bad idea as we store data for each session in the reportservertempdb database until the session expires: You'd be holding onto data for every single connection ever made to SSRS for a year at a time :)
You can keep the session alive by simply pinging the SSRS web service now and then (maybe return a list of folders or something with the ListChildren method call) using the SessionID. If you do every 10 minutes (the default timeout), the session will stay up.

Thanks for the comment Russell. After making the change to 525600 (1 year) if I set it back to defalt would that clean up the Temp DB? for any sessions that were kept.
Reason I need this value big is because these ID's are hard coded in the Visual Studio Team Tester, since they are dynamic in nature I can create the script (which would have hard coded dynamic IDs) but the script would fail as soon ID's expire. So for now solution is keep it alive as I run though my load test and reset it back to 10 min once I am done with the load test :) what do you think!!!

I honestly don't know - I assume it would, but since I've never tried it myself, who knows :)

It won't. The expiration time is computed when the session is created.
Can you provide an example of the URL which VSTS generates and the steps you went through in VSTS to generate it?

Hi John, Here is the request that VSTS records when you are creating the script. Performance requirements for this particular report are that 450 users should be able to run this report for 4 hours, to fulfil this requirement I created a .webtest that goes to reports URL and once script is recorded one of the request looks like
GET /Reports/Reserved.ReportViewerWebControl.axd?ReportSession=o2k22t45jovswpqfkyswbn45&ControlID=d78e217e-d7f3-4952-ad32-cc9f6bb483f6&Culture=1033&UICulture=9&ReportStack=1&OpType=SessionKeepAlive&TimerMethod=KeepAliveMethodctl160TouchSession0&CacheSeed=Thu%20Feb%2022%2010%3A20%3A18%202007
Report Session and Control ID in this request are dynamic and change every few mins. once I try running this script after few hours these request (with session ID hard coded start failing). So I asked the question on the forum on how to keep the session alive for long time so I can get through my Performance testing cycle (next couple of months).
With respect to load testing with 450 users VSTS will simulate same user 450 times so only one session ID will live for 1 year but you would probably know better what would the Temp DB look like after the script is done running for few hours. One thing I did notice from the rsreport.config file it did not had any SessionTimeout key, it has the following though.
<Add Key="CleanupCycleMinutes" Value="10"/>
<Add Key="SQLCommandTimeoutSeconds" Value="60"/>
<Add Key="MaxActiveReqForOneUser" Value="20"/>
<Add Key="DatabaseQueryTimeout" Value="120"/>
<Add Key="RunningRequestsScavengerCycle" Value="60"/>
<Add Key="RunningRequestsDbCycle" Value="60"/>
<Add Key="RunningRequestsAge" Value="30"/>
<Add Key="MaxScheduleWait" Value="5"/>
Does this mean I have to add SessionTimeout key or first key above "cleanupcycleminutes" is the same as SessionTimeOut key.
Thanks for your input.

The "SessionTimeout" is a system property. You have to set it via SOAP API or rs.exe
