Need some urgent help

Hi,
Your article is wonderful. Very useful. But with my issue I still don't have resolution. It would be good if you can through some light on it.
We use:
ASP.NET 6.0, State Server to store sessions and IIS 6.0.
A single server as - web as well as state server. No farm nothing.
Issue is we physically moved the severs to a new data center. Suddenly we have started observing session data getting lost. Behaviour is random and not getting replicated on any of the dev servers. Also many a times only part of the session data is lost and not all the values. It's strange. I do not want to enable application level trace on production as well performance monitor tool does not seem to be helping in my case.
Can you help out with the issue. Suggest some external tool which monitors the issue or is it possible to write small .NET app to trace the existing web app.
Your suggestions are valuable.
Thank you.

Hi Payal,
If you are seeing shared sessions, the first thing that you should check is Caching. See if you have Caching enabled and proceed form there.

Hi Rahul,
This is article gives me a lot of insight for using session or resolving session related issue. But i am facing some major problem with session state in asp.net 1.1 application.
Session variables are conflicting with each other that means if there are two/three simultanous user using the web application at same time, some times they can view the details of other users and vice-versa. When i debug the application i hv not found any issues. I am just storing employee ID which is numeric. Can you please help me to resolve this issue?
thanks

Web Farm - Complex object storing issues

Hi Senthil,
Server.Transfer is executed at the server side, which means that the code would execute on the server which is catering to the request. Response.Redirect might end up on a new server, but Server.Transfer wouldn't.
Regarding the 2nd query, you need to ensure that the objects are serializable, else you would see an error message while trying to store that objects in the session.
But honestly, try NOT to store very large objects, specially you should always ensure that whatever you are storing in session is short and sweet. Large session objects (> 85K) would end up in LOH and hence complicate your App's memory requirements.
HTH,
Rahul

Rahul,
Article looks great, our problem is here:
"Notice… it is not a problem which “All the users face at the same time.” It is something which is happening to ALL the users, BUT NOT AT THE SAME TIME."
But it seems the article is not giving tips for this scenario or I missed sth.
Your advice will be helpful.

Hi Mihir,
In fact, ASP.NET and ASP.NET Applications are not generic, and they are supposed to show the Perfmon as per your observation. That is, it will show the counters for the latest version of .NET Framework installed on your box.
If you have 1.1 and 2.0 both, it won't show any 1.1 counters. If you need to see 1.1 counters, you will need to add them explicitly.
Hope that helps,
Rahul

Asp.Net and Asp.Net Applications are generic ?

Hey Rahul,
Nice two see this article.
I have some concern here..any internal article will help.
I'm using PERFMON utility to measure performance of an asp.net application with Asp.Net and Asp.Net Applications performance objects (attribute group) of PERFMON Utility. I've deployed 2 same Asp.Net application on my machine, the only difference is one is developed using Asp.Net 1.1 and the other is developed using Asp.Net 2.0. Through observation I've noticed one thing that's Asp.Net and Asp.Net Application attribute group reflects the values same as Asp.Net 2.0. and Asp.Net Apps 2.0 attribute group and not refecting the values those are of Asp.Net 1.1.4322 and Asp.Net Apps 1.1.4322 attribute groups.
My understanding for this is Asp.Net and Asp.Net Applications are generic attribute group(Performance Objects) and they should refelect values of both attribute groups (Asp.Net 1.1.4322 and Asp.Net 2.0 as well Asp.net Apps 1.1.4322 and Asp.Net Apps 2.0). I've all 3 versions of .Net installed on my machine but I'm not getting any attribute group specific to Asp.Net 3.0 like previous two.
Can anyone make me clear on which attribute group to use for measuring performance of various Asp.Net Application i.e. Generic one or Version Specific? Because the Perfmon utility shows both generic i.e ASP.NET
and version specific performance objects like (ASP.NET v1.1.4322)
I am stuck please help.

I guess, I missed this very important KB article
http://support.microsoft.com/?id=184574. It talks about certain cases where you will have multiple ASPSessionID cookies. As you know a lot of cookies might hurt the performance, and it could also lead to Session Loss.
Just thought I should addding this information here!
