Frustrated!! 500 internal server error

[Helpneeded]

I am using ASP.NET Ajax timer on my web page. The web page refreshes
after the timer expires. The page runs smoothly but after some time I
get the dreaded "500 server error" with the following description:

"code=[SERVER_RESPONSE_CLOSE] The server closed the connection while
reading the response. Contact your system administrator."

I have been trying to fix this problem for 2 weeks now and am really
frustrated. Please help me.

I am running IIS 5.1 on Windows XP SP2!

Hi

See the event log on the server and post related entries here.

this means the page is generating an error. a common cause is lost
session and your page code not handling it.

note: the timer and update panel do not update the session cookie timeout.

How do I reset the cookie timeout on every refresh?

note: the timer and update panel do not update the session cookie timeout.

The event log is blank. It does not show any related message.
