On PHP pages that I get control over, one of the first things I do is add Gzip encoding. This compresses the text on the page for browsers that can handle it, and really reduces network traffic, speeding up page load\/download times on dial-up (well, and broadband) connections significantly.<\/p>\n

On PHP this is really easy, its just one line of code at the top of the page:<\/p>\n

ob_start('ob_gzhandler');<\/pre>\n
But until now, I had trouble finding out how to do this for .NET sites.  All I could find was that you can enable it server-wide on IIS but now I found this handy bit of code that can go at the top of your .NET pages.<\/p>\n
string AcceptEncoding = HttpContext.Current.Request.Headers[\"Accept-Encoding\"];\r\nif (!string.IsNullOrEmpty(AcceptEncoding) && AcceptEncoding.Contains(\"gzip\"))\r\n{\r\n    HttpContext.Current.Response.AppendHeader(\"Content-Encoding\", \"gzip\");\r\n    HttpContext.Current.Response.AppendHeader(\"Vary\", \"Content-Encoding\");\r\n    HttpContext.Current.Response.Filter = new System.IO.Compression.GZipStream(HttpContext.Current.Response.Filter, System.IO.Compression.CompressionMode.Compress);\r\n}<\/pre>\n
And that’s it.  Tasty Gzip encoding for all.  The next step is testing it, which I use the mod_gzip_test site for.  You can see an example of the changes we made to gameplayer.co.nz (a .net site) here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
