(Bug?) IIS Sends response to wrong client

[Gilles]

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.Session ID);

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

Gilles,

Do you have any kind of caching enabled?
Like page or fragment caching?

Or do you have a proxy/caching server between you and the web server?

Hello Geir,
Thanks for your answer.
The application is on our intranet and in my knowledge, there is no proxy
server in there.
I put <%@ OutputCache Duration="1" VaryByParam="none" %> in the Page
directive.
But maybe there is something I missed in the Web server config.

Why even put in an outputcache declaration at all when you are trying something like this ?
Most likely you are caching and that is the issue you are seeing.

Thanks you all, I've found the answer thanks to your suggestions,
I thought that the directive <%@ OutputCache Duration="1" VaryByParam="none"
%>
prevents caching, but I wa wrong.
I replaced the directive with <%@ OutputCache Location="None"
VaryByParam="None" %> and it works now.
