mvc开启gzip压缩示例分享

//如果出现错误，则不进行压缩，否则页面会出现乱码，而不是报错的黄页
if (filtercontext.exception != null)
return;

//判断iis或者其他承载设备是是否启用了gzip或deflatestream
if (response.filter is gzipstream || response.filter is deflatestream)
return;
//开始进入压缩环节
string acceptencoding = filtercontext.httpcontext.request.headers["accept-encoding"];
