Re: Bug in HttpWebRequest/Response Dispose() implementation?

Well, the problem we discovered was actually in our code running on .NET 2.0
:-(

We will investigate more, but first impression - the problem is still there,
since "using" does not work and GC.Collect does.

I am not in the office right now, but I guess the original code looked
like
this:

HttpWebRequest request = PrepareRequest(...);
using(HttpWebResponse response = (HttpWebResponse)request.GetResponse())

... do something with response
}

HttpWebRequest is not disposable, so we applied "using" pattern to
HttpWebResponse object only.

While searching for the source of the problem, I found couple of
documents:

http://support.microsoft.com/?kbid=831138

Looks like there .NET 1.1 had a problem with release of unmanaged
resources
allocated by HttpResponse. Does .NET 2.0 has the same problem?

Hmm. Glad you've found it. I *suspect* that .NET 2.0 doesn't have the
same problem, given that it was fixed against 1.1 in the hotfix. I
wouldn't like to say for sure though.
