           Summary: HttpListener returns HTTP 400 when wildcard is used
                    for host name and path exists
    Classification: Mono

           Version: unspecified

          Priority: P5 - None

The following HttpListener use case demonstrates that an HttpListener that is
given as a prefix that is a wildcard host name, suffixed with a subpath
(http://*:8080/foo). HTTP request to the server results in 400 (Bad Request).

Wildcard prefix with path does not result in failure, but this example is
reproducible.

                tw.Write ("<s:Envelope

            ctx.Response.Close ();
            l.Close ();
            Thread.Sleep (1000); // This sleep is required (even on .NET) to
give some delay for something.

public class Test
{
    public static void Main ()
    {
        for (int i = 0; i < 2; i++) {
            var hr = (HttpWebRequest) WebRequest.Create (new Uri
("http://localhost:8080/" + (i == 0 ? "foo" : "bar")));
            hr.Method = "POST";
            hr.KeepAlive = false;
            hr.ContentType = "text/xml; charset=utf-8";
            hr.Headers ["SOAPAction"] = "\"urn:foo\"";
            var rs = new StreamWriter (hr.GetRequestStream ());
            rs.WriteLine (@"<s:Envelope
xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'>
  <s:Header>
  </s:Header>
  <s:Body />
</s:Envelope>");
            rs.Close ();
            var rr = new StreamReader (hr.GetResponse ().GetResponseStream ());
            Console.WriteLine (rr.ReadToEnd ());
            rr.Close ();
        }
    }
}

On .NET, two requests and replies are processed as expected. On Mono, first
request fails.

Some notes:
- I (again) tried it on Windows, so it may work fine on other platforms.
- The repro kind of replicates WCF BasicHttpBinding; there's couple of
extraneous code I know.
- Actually the loop (i<2) doesn't matter. It fails at the first request.
- I set a blocker for bug #687580. That bug could be fixed by switching #if
false to #if true in System.ServiceModel.Channels.Http/HttpListenerManager.cs
line 113.
