Client request is processed twice

[Olivier Matrot]

Hello,
I have a problem with an ASP.NET 2.0 Application.
A client request is processed in parrallel by two threads.
This ends with the following exception :

More information :
After further analysis, it appears that :
- There is 2 disctinct session for the request (Session_Start in
global.asax)
- One of the session ends (Session_End in global.asax).
- The ramining session is used for subsequent requests, and everything works
fine.

IMO you'll have to explain a bit what you meant or how you do :
- A client request is processed in parrallel by two threads
- There is 2 disctinct session for the request
or what it your overall goal.

The standard situation is that an HTTP request is processed by a single
thread and is binded to a single session so it would seems you try something
special. My first thought would be that you try to add the same key twice in
distinct threads when you have a single request coming and that the
clientscriptman ager is likely not designed to handle such an unusual
situation

It's likely that your best bet is first to explain what you are trying to do
so that we can better grasp the context (you have build in capabilites for
async processing in .NET 2.0 that you could perhaps use ?)...

My goal is not to have a client request processed twice.
This is a weird behavior I have on my web site.
This is happening primarily when the application is started for the first
time, but sometimes it is on a simple page request. No page in particular is
concerned, and I can't reproduce it myself.
My application generates a log file, and the facts exposed here are clearly
visible in that file.
The IIS log file shows that only one request is comming from the client.
Take a look at the following :

Humm... Never seen this.

My first thought would be having the ASPX page handler registered twice ?
But as you don't have this yourself perhaps those users are behind a network
equipement such as a proxy. But then the IIS log show anyway a single
request so it would be something server side ?

Really weird...

Good luck.

>IMO you'll have to explain a bit what you meant or how you do :
- A client request is processed in parrallel by two threads
- There is 2 disctinct session for the request
or what it your overall goal.

The standard situation is that an HTTP request is processed by a single
thread and is binded to a single session so it would seems you try
something special. My first thought would be that you try to add the same
key twice in distinct threads when you have a single request coming and
that the clientscriptman ager is likely not designed to handle such an
unusual situation

It's likely that your best bet is first to explain what you are trying to
do so that we can better grasp the context (you have build in capabilites
for async processing in .NET 2.0 that you could perhaps use ?)...

>>More information :
After further analysis, it appears that :
- There is 2 disctinct session for the request (Session_Start in
global.asax )
- One of the session ends (Session_End in global.asax).
- The ramining session is used for subsequent requests, and everything
works fine.
