Session Time Out Issue In ASP.NET hosted in Windows 2003 Enterprise Edition

[Vasu]

Hi All,

My ASP.NET website is running on .NET 1.1. hosted in windows server
2003
enterprise edition. We are having two sites. They are

1. One internet site
2. One intranet site.

Both these sites are having same aspx pages. No difference at all
between them in page content.

My business logic is hosted as web service which is running in the
intranet site. My intranet site web server also hosts a legacy web
speed
application whose authentication is controlled by the new ASP.NET
application. This is being achieved through setting some cookies.

Most of my ASPX pages are popup pages.

We are facing one peculiar problem in the intranet site. After
authentication When ever a user clicks any one of the links of the
popup
windows the session is getting timed out. But when we navigate with
normal pages this does not happen.

This problem occurs only in the intranet web server where my web
service and the legacy wep speed application is hosted.

The same asp.net code which is hosted in internet web server does bot
pose any problem.

Last time when we had this prolem we have replaced the dlls which are
working fine in the internet site to the intranet site virtual
directory. Then this problem was solved. But now after some time this
problem is coming again in the same pattern.

Could any one thorw some light on this?

Early response is appreciated.

with regds,
Vasu
