. Net mvc simple implementation GZIP

We all know the benefits of GZIP, but in general, the page is not too big, and many people have not paid attention to this. Some time ago, I made a system using a JQUERY rich client framework developed by a Chinese people (I personally think this framework is quite good), similar to the AJAX framework of EXT, the JS of the framework, coupled with my own, is really not small.

 

 

I plan to use GZIP for compression. I have done it on IIS6 before. This project is implemented using MVC and found in. net mvc has a simpler and easier way to solve the problem: Write an ActionFilter to implement GZIP. You will know the advantages when you use it.

 

    public class CompressAttribute : ActionFilterAttribute    {        public override void OnActionExecuting(ActionExecutingContext filterContext)        {            var acceptEncoding = filterContext.HttpContext.Request.Headers["Accept-Encoding"];            if (!string.IsNullOrEmpty(acceptEncoding))            {                acceptEncoding = acceptEncoding.ToLower();                var response = filterContext.HttpContext.Response;                if (acceptEncoding.Contains("gzip"))                {                    response.AppendHeader("Content-encoding", "gzip");                    response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);                }                else if (acceptEncoding.Contains("deflate"))                {                    response.AppendHeader("Content-encoding", "deflate");                    response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);                }            }        }    }

Usage:

        [Longin]        [Compress]        public ActionResult Index()        {                            return View();        }

You only need to write [Compress] on the Action to be compressed using GZIP. Is it very simple ~
