Hi,
Please add below code in your Global.asax file and check -
voidApplication_PreRequestHandlerExecute(objectsender,EventArgse)
{
HttpApplicationapp=senderasHttpApplication;
stringacceptEncoding=app.Request.Headers["Accept-Encoding"];
System.IO.StreamprevUncompressedStream=app.Response.Filter;
if(app.Context.CurrentHandler==null)
return;
if(!(app.Context.CurrentHandlerisSystem.Web.UI.Page||
app.Context.CurrentHandler.GetType().Name=="SyncSessionlessHandler")||
app.Request["HTTP_X_MICROSOFTAJAX"]!=null)
return;
if(acceptEncoding==null||acceptEncoding.Length==0)
return;
acceptEncoding=acceptEncoding.ToLower();
if(acceptEncoding.Contains("deflate")||acceptEncoding=="*")
{
//deflate
app.Response.Filter=newSystem.IO.Compression.DeflateStream(prevUncompressedStream,
System.IO.Compression.CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding","deflate");
}
elseif(acceptEncoding.Contains("gzip"))
{
//gzip
app.Response.Filter=newSystem.IO.Compression.GZipStream(prevUncompressedStream,
System.IO.Compression.CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding","gzip");
}
}

Somehow, I just don't remember writing any piece of code to implement compression. It's all configuration based and pretty much automatic between client -> server -> client communication (i.e. request and response).

I personally believe that you will need to enable http compression on server (IIS) level. If it is disabled on server level, just placing above contents in web-site config file will (i doubt) not enable compression as lower level config cannot override (unless authorized) higher level settings.
