Question

I am trying to GZIP some XML that gets streamed over HTTP (not a web service)

if (ZipOutput)
{
    output = new GZipStream(Context.Response.OutputStream, CompressionMode.Compress);
    Context.Response.AppendHeader("Content-Encoding", "gzip");
}
else
{
    output = Context.Response.OutputStream;
}

EscapeXMLTextWriter xmlWriter = new EscapeXMLTextWriter(output, new UTF8Encoding())
{
    Formatting = Formatting.Indented
};

ZipOutput is true, but the response doesn’t seem to be zipped. Any pointers, alternative techniques?

I know I could use SharpZipLib, but wanted to use the GZipStream class in the framework.

I figured this issue out I think – it turned out the office firewall was stripping the Accept-Encoding header on outbound requests.
