Has Anyone Got HTTP Compression Working with ASP.NET? -

i've spent quite bit of time on seem going nowhere. have large page want speed up. obvious place start seems http compression, can't seem work me.

after considerable searching, i've tried several variations of code below. kind of works, after refreshing browser, results seem fall apart. turning garbage when page used caching. if turn off caching, page seems right lose css formatting (stored in separate file) , error included js file contains invalid characters.

most of resources i've found on web either old or focused on accessing iis directly. page running on shared hosting account , not have direct access iis7, it's running on.

protected void application_beginrequest(object sender, eventargs e) {     // implement http compression     if (request["http_x_microsoftajax"] == null) // avoid compressing ajax calls     {         // retrieve accepted encodings         string encodings = request.headers.get("accept-encoding");         if (encodings != null)         {             // verify support or gzip (deflate takes preference)             encodings = encodings.tolower();             if (encodings.contains("gzip") || encodings == "*")             {                 response.filter = new gzipstream(response.filter,                     compressionmode.compress);                 response.appendheader("content-encoding", "gzip");                 response.cache.varybyheaders["accept-encoding"] = true;             }             else if (encodings.contains("deflate"))             {                 response.filter = new deflatestream(response.filter,                     compressionmode.compress);                 response.appendheader("content-encoding", "deflate");                 response.cache.varybyheaders["accept-encoding"] = true;             }         }     } } 

is having better success this?

i've had results using gzipstream , deflatestream write output directly, although i'm not familiar response.filter property. give whirl:

string response = "your output body"; string accept = request.headers["accept-encoding"]; if(accept == null) accept = ""; if (response.length < 100 || !(accept.contains("deflate") || accept.contains("gzip")))     response.write(response); else {     byte[] compressed;     bool usedeflate = accept.contains("deflate");     using (memorystream stream = new memorystream())     {         using (stream deflate = usedeflate             ? (stream)new deflatestream(stream, compressionmode.compress, true)             : (stream)new gzipstream(stream, compressionmode.compress, true))         using (streamwriter writer = new streamwriter(deflate))             writer.write(response);         compressed = new byte[stream.length];         stream.position = 0;         stream.read(compressed, 0, compressed.length);     }     response.headers["content-encoding"] = usedeflate ? "deflate" : "gzip";     response.binarywrite(compressed); }
