Strange session problem

[Wim Geukens]

Hi,

We're experiencing a very strange session variable problem.
We've got a running version of our site at www.mysite.com, which points to
c:\mysite in IIS 5
This same site is also reachable via test.mysite.com, because we specified
it in the "Advanced multiple Web Site configuration" dialog box.
So it's basically the same website.

Now, on our site we have a datagrid with paging enabled.
When, for example, going to page 8, then clicking on an item which opens a
new page and then from within that page returning to the page with the
datagrid (Response.Redirect), it goes back to page 1 instead of page 8.
We're using a Session variable called PageNr to keep track of the page that
the user was on.

The weird thing now is that when we're using the URL test.mysite.com
everything works fine.
When we're using the URL www.mysite.com, the problem appears.

We're using IIS 5, ASP v1.0 on a Windows 2000 Server.

Does anyone have an idea what might cause the problem?

Thanks in advance
Wim
