Decompress a GZipped response from the server (Socket) - c#-3.0

Question

Umm, ok, after sending some data to the server, noting this particular part:
"Accept-Encoding: gzip,deflate\r\n"
I am getting the following response:
HTTP/1.1 200 OK
Server: nginx
Date: Fri, 09 Apr 2010 23:25:27 GMT
Content-Type: text/html; charset=UTF-8
Transfer-Encoding: chunked

But how do I decompress it? Note that I am using the Socket Class to do all the work.
I know how to decompress it, but the problem here lies in the fact that I cannot separate the Packet from the GZipped data, psuedo-psuedocode (or whatever) on how I do it:
Socket sends packet;
Socket reads response from server, stores into a ByteArray;
Create MemoryStream, use ByteArray;
Create GZipStream, use Memorystream;
now the problem occurs; I am getting the following Error:
System.IO.InvalidDataException
The magic number in GZip header is not
correct. Make sure you are passing in
a GZip stream.
I hope the explanation is clear enough >__>.

Answer 1

The content that you need to gzip begins after a double-newline, and goes for (if present) Content-Length bytes. You might start there.
Is it possible for you to use System.Web.HttpRequest? It will take care of a lot of the administrative details of parsing the response for you...
Or do you have to use raw Sockets?
