启用gzip,deflate压缩可以减少相应的传输量,MVC可以通过自定义actionfilter实现

 

using System.IO; 
using System.IO.Compression;  
 
public class EnableCompressionAttribute : ActionFilterAttribute 
{ 
    const CompressionMode compress = CompressionMode.Compress; 
    public override void OnActionExecuting(ActionExecutingContext filterContext) 
    { 
        HttpRequestBase request = filterContext.HttpContext.Request; 
        HttpResponseBase response = filterContext.HttpContext.Response; string acceptEncoding = request.Headers["Accept-Encoding"]; 
        if (acceptEncoding == null) 
            return; 
 
        if (acceptEncoding.ToLower().Contains("gzip")) 
        { 
            response.Filter = new GZipStream(response.Filter, compress); 
            response.AppendHeader("Content-Encoding", "gzip"); 
        } 
        else if (acceptEncoding.ToLower().Contains("deflate")) 
        { 
            response.Filter = new DeflateStream(response.Filter, compress); 
            response.AppendHeader("Content-Encoding", "deflate"); 
        } 
    } 

}
