Having a problem using WebRequest inside code invoked by the Page_Load event to to download a page l

[Guest]

I have a website with 2 aspx pages
Foo.aspx, and bar.aspx
The content of both files
is

//in 1 file
Hello <%=Session["Name"].ToString()%>


================
Here's the problem, inside the Page_Load for
Foo.aspx, using the HttpWebRequest, I do a request
to bar.aspx, passing in the session cookie. A timeout occurs.
When I use a debugger and set a break point at bar.aspx's Page_Load,
the breakpoint is reached only after the HttpWebRequest throws a timeout
exception inside Foo.aspx's Page_Load. Setting the timeout to higher numbers
has no effect. Creating a webrequest to a page not on the same server as
mine does not generate an error. e.x.: downloading cnn.com's homepage from
within Foo.aspx will work. Does anyone know why this would happen. Please
post back if any clarification is needed.
I feel it may have something to do with the thread process used by iis
and/or aspnet.

It's sort of like the problem that's reported here ->

I'm using winxp pro w/ .net 1.1 and vs.net 2003. Everything .net related
should be running in debug mode.

You should probably use Server.Transfer() to transfer control from foo.aspx
to bar.aspx.

I can't because I want to download the rendered page (bar.aspx from inside
foo.aspx).

You should probably use Server.Transfer() to transfer control from
foo.aspx
to bar.aspx.

i have used WebClient to fetch a rendered page.
I normally use
http://www.domainname.com/pagename.aspx to open the webclient and then read
the data.
leave it to do the dns query and resolution.

though with webclient i never had to bother with session cookies etc

I would also like to add that, when in debugging
If inside Foo.aspx, I say Thread.Sleep(); while Foo.aspx is sleeping, I open
IE using and go to Bar.aspx and it hangs (as if IIS hasn't processed by
request, and I think it's because Thread.SLeep() was being executed in
Foo.aspx) which was called by a different browser window.

interesting.. I'm going to check my iis settings. it's as if my iis server
is single threaded.

IE uses a common process for http requests (by design to implement the
limited connection rule), so that even if you use more than 1 browser
instance, if your breakpoint blocks a request, all browsers are blocked.

Running it without being attached from a debugger produces the same result.
If I switch the application to cookiless where the session id is passed
around through the url, it seems to work but unfortunately, I have to store
the session id in cookies.

I thank everyone for their input and timely response.

if you use webclient, your code is responsible for sending any cookies.

Yes, I'm aware of this. I use a httpwebrequest object and copy cookies from
the HttpRequest.Cookies object.
