Reusing HttpWebRequest. GetRequestStrea m

[Dan]

I'm experimenting with HttpWebRequest. After I've created a request:

m_request = (HttpWebRequest ) WebRequest.Crea te(uri);

I'd like to repeatedly send requests to the URI, as follows:

public void SendRequest(str ing body)
{
StreamWriter stream = new
StreamWriter(m_ request.GetRequ estStream(),Enc oding.ASCII);
stream.Write(bo dy);
stream.Close();
}

However, the second time I send the request I get the following exception:

An unhandled exception of type 'System.Argumen tException' occurred in
mscorlib.dll
Additional information: Stream was not writable.

Does anybody know why that happens?
Thanks...

That is part of the HTTP protocol. After a Web request is made, the underlying connection is closed unless the client specifies to keep it open for a period of time. You can request the connection to stay open by setting the Connection property of the HttpWebRequest object to "Keep-alive"

Thanks. However, when I set the connection property to "Keep-Alive", I got
the following exception: "Keep-Alive and Close may not be set with this
property."

I also tried setting the KeepAlive property to true, which made no
difference: I still got the "Stream was not writable" exception.

I don't think its possible to reuse the request stream. Instead, just create
a new (Http)WebReques t instance.
