We have a .NET 1.1 client which is sending a gzipped soap request using
HttpWebRequest to an Apache server. The Apache server is using a the
'mod_deflate' server to decompress the incoming message, and to also compress
the response (GZIP).

The mod_deflate filter requires the 'Content-Length' header contained within
the incoming request to specify the number of UNCOMPRESSED bytes being sent
and not the actual bytes of the body of the compressed HTTP request itself.
The problem we have is .NET requires that you specify the number of actual
bytes written to the request stream as specified in the Content-Length header
of the request message. The exception we receive when attempting to close
the stream to send the request is:

    [System.IO.IOException]: {System.IO.IOException}
    HelpLink: Nothing
    InnerException: Nothing
    Message: "Cannot close stream until all bytes are written."
    Source: "System"
    StackTrace: " at System.Net.ConnectStream.CloseInternal(Boolean
internalCall, Boolean ignoreShutDownCheck)"
    TargetSite: {System.Reflection.RuntimeMethodInfo}

Is there any way around this issue?
