How to enable gzip compression in asp.net mvc
Soluiton:
just add this function in global.asax.cs file
void Application_PreRequestHandlerExecute(object sender, EventArgs e)
{
var app = sender as HttpApplication;
if (app != null)
{
string acceptEncoding = app.Request.Headers["Accept-Encoding"];
Stream prevUncompressedStream = app.Response.Filter;if (!(app.Context.CurrentHandler is Page ||
app.Context.CurrentHandler.GetType().Name == "SyncSessionlessHandler") ||
app.Request["HTTP_X_MICROSOFTAJAX"] != null)
return;if (string.IsNullOrEmpty(acceptEncoding))
return;acceptEncoding = acceptEncoding.ToLower();
if (acceptEncoding.Contains("deflate") || acceptEncoding == "*")
{
// defalte
app.Response.Filter = new DeflateStream(prevUncompressedStream,
CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "deflate");
}
else if (acceptEncoding.Contains("gzip"))
{
// gzip
app.Response.Filter = new GZipStream(prevUncompressedStream,
CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "gzip");
}
}
}
