If you are getting the error

that blah blah blah...

I suggest you figure it out yourself, and stop wasting everyone's time.

Alternatively, you could post sample code and a real error message, and
perhaps someone will help you.

Hi,

As far as I know you can’t access Session from another thread directly
or by using HttpContext.Current, you should get null from
HttpContext.Current. The work around that I use is to pass the Context
as parameter to the thread.

see my sample : [url]http://www.developersdex.com/gurus/code/662.asp[/url].

Hi,

Thanks, but i noticed that u need to have the Join method or else the
HttpContext.Session will still be null. Wouldn't that defeat the
purpose of multithreading then?

If you spawn the thread and don't wait, then whats the point. The page will
get served without your thread ever getting back. Then all the processing
that you are doing in the thread is waste. At some point you will have to
wait for the threrad to finish execution.
