Session Stage\Variables

[Rick]

We are in the process of testing a large web project that I converted from
VS 2003 to VS 2005. Everything seems to be working except for a few minor
things. But the main issue I have is this, I have about 5 or 6 developers
testing this web site in a staging environment on a Microsoft 2003 Server
box. We have a base page that gets called on every page and checks for
session variables. After about 20 - 30 minutes these session variables are
getting cleared out and throwing an "object reference not set to an instance
of an object" error, this is due to the session variable all of sudden no
longer exists, This was not an issue with 2003.

I have sessionstate enabled and set to timeout at 20. My understanding is it
shouldn't time out for everyone at the same time and should time out if the
session is active.

Leading up to the time the error shows, I get this error in the eventlog:

You set the timeout for 20 minutes and you say it starts throwing errors
after 20 minutes? Uh, isn't that what you would expect?

Also, why aren't you trapping for the existance of the session variable
prior to trying to access it? That has been an issue since for over
6 years now. That's not new in .NET 2.0.

You could also paste this in your global.asax and log the
error.

using System.Diagnost ics;

protected void Application_Err or(object sender, EventArgs e)
{
Exception objErr = Server.GetLastE rror().GetBaseE xception();
string err = "Error Caught in Application_Err or event\n" +
"Error in: " + Request.Url.ToS tring() +
"\nError Message:" + objErr.Message. ToString()+
"\nStack Trace:" + objErr.StackTra ce.ToString();
EventLog.WriteE ntry("Sample_We bApp",err,Event LogEntryType.Er ror);
Server.ClearErr or();
//additional actions...
}

You may have an unhandled error somewhere in the app
that is causing IIS to shutdown the app pool (which will kill
InProc Session) and restart it.

The main difference between .NET 1.1 and .NET 2.0 (VS 2003 and VS 2005) is
that if you had a worker thread and it throws unhandled exception then the
whole process is terminated. It was not the case with .NET 1.1

In IIS environment the process is restarted instead of simple shutdown but
Session variables are lost and exception (similar to yours) is logged into
NT event log.

So look if you have a worker threads and enclose them into try.. catch...

PS: worker threads are the ones that you created yourself. Normal flow of
ASP.NET pages are normal threads and ASP.NET aware of them and catches all
exception thrown for you.

True. One possiblity "might" be Server.Transfer and Response.Redire ct
and not using a return statement right afterwards.

Response.Redire ct("blah.aspx", false);
return;

I've seen this throw exceptions if the return line is missing.

I do not believe that it throws an unhandled exception.
It will not terminate the process.
Might give the user an error message but sessions will be intact.

But it's not unhandled.....
it's catched inside of ASP.NET framework...

am i right? Only unhandled, ie the ones that go without catch, are
dangerous.

Thanks for the input!
Here is one thing I discovered with the code(by the way I didn't write this
it was inherted from other developers who are no longer here).
We have a data layer that accepts queries and excecutes them etc ...
Within this data layer the exceptions are handled and logged to the event
log. within the try catch after logging the exception, the code throws a new
exception to bubble up to the calling class, this is were I am getting an
unhandled exception error. So, this worked in 1.1 and bubbled the exception
but now it doesn't in 2.0. What is the correct way to accomplish this?

Sample Code:

Try
runSQL(SQL)
Catch EX as exception
logexceptionfro mDatalayer(EX)
End Try
Public Function runSQL(ByVal SQL As String) As Boolean

Try

execute the query here

Catch ExceptionObject As Exception

logexception(Ex ceptionObject )

Throw New Exception("Data LayerName", ExceptionObject )

Finally

'Clean up

End Try

End Function

>We are in the process of testing a large web project that I converted
from VS 2003 to VS 2005. Everything seems to be working except for a few
minor things. But the main issue I have is this, I have about 5 or 6
developers testing this web site in a staging environment on a Microsoft
2003 Server box. We have a base page that gets called on every page and
checks for session variables. After about 20 - 30 minutes these session
variables are getting cleared out and throwing an "object reference not
set to an instance of an object" error, this is due to the session
variable all of sudden no longer exists, This was not an issue with 2003.

I have sessionstate enabled and set to timeout at 20. My understanding is
it shouldn't time out for everyone at the same time and should time out
if the session is active.

Leading up to the time the error shows, I get this error in the eventlog:

this is correct approach.
I am not sure why you saying it's not working...... I do not see any obvious
problem....

The only reason I might suggest is that your logexception is throwing some
other error so it actually never makes to your next statement
Throw New Exception("Data LayerName", ExceptionObject )

Thanks for the input!
Here is one thing I discovered with the code(by the way I didn't write
this it was inherted from other developers who are no longer here).
We have a data layer that accepts queries and excecutes them etc ...
Within this data layer the exceptions are handled and logged to the event
log. within the try catch after logging the exception, the code throws a
new exception to bubble up to the calling class, this is were I am getting
an unhandled exception error. So, this worked in 1.1 and bubbled the
exception but now it doesn't in 2.0. What is the correct way to accomplish
this?

Sample Code:

Try
runSQL(SQL)
Catch EX as exception
logexceptionfro mDatalayer(EX)
End Try
Public Function runSQL(ByVal SQL As String) As Boolean

Try

execute the query here

Catch ExceptionObject As Exception

logexception(Ex ceptionObject )

Throw New Exception("Data LayerName", ExceptionObject )

Finally

'Clean up

End Try

End Function

>The main difference between .NET 1.1 and .NET 2.0 (VS 2003 and VS 2005)
is that if you had a worker thread and it throws unhandled exception then
the whole process is terminated. It was not the case with .NET 1.1

In IIS environment the process is restarted instead of simple shutdown
but Session variables are lost and exception (similar to yours) is logged
into NT event log.

So look if you have a worker threads and enclose them into try.. catch...

PS: worker threads are the ones that you created yourself. Normal flow of
ASP.NET pages are normal threads and ASP.NET aware of them and catches
all exception thrown for you.

I walked through the code line by line, It is making it to the next
statement, then as soon as it breaks on the finally it throws an Exception
was unhandled by user code error
