LOL!  Does it work with worker processes set to 1?

If you are using multiple worker processes I think you may need to use a session service.  There could be a problem with the request going to a different  process than the one that created the session.

Response.Redirect will end the response by default.

Use Response.Redirect("detail.aspx", false);

   Session("ID") = 43;

Look over your debug output.  Is something causing the application to reset?

Other possibilities:

Look over IIS settings, and especially application pools.  Are you using web farm/garden (max. worker processes > 1)?

Check your host name for invalid characters.  Apparently this can interfere with cookies.

do you have EnableSessionState="True" in <@Page... directive?

use Response.Redirect("detail.aspx", false);

Delete cookeis and than try again.

We are using web garden as 5

EnableSessionState="True and  web garden as 500 doesn't help

process set to 1 also doesn't work
everything doesn't work except server.transfer

After you make the IIS change restart the server.
