Hello,
I discovered a strange behaviour (bug?) in IIS 5.0 and asp.net 1.1.
- user A clicks on a link requesting page x.
- user B clicks simultaneously (1/10th of second later)on the same link.
- user A receives the expected response.
- user B receives the response of A.
the Page_Load of page x.aspx contains:
Response.Write(HttpContext.Current.Session.SessionID);

I posted this question in the microsoft.public.inetserver.iis group, but
nobody seems to be interested to answer, I hope receiving guidelines here.

Could you please help ?

Thanks

Gilles
