无需访问服务器配置即可对asp.net mvc 2进行GZip或Deflate压缩

Question

我试图使用这里描述的方法ASP.NET MVC Action Filter - Caching and Compression.起初,结果令人鼓舞,因为服务器确实开始发送GZip编码文件,但经过进一步测试,有时,在带有Html.RenderAction部分的页面中,该属性将被调用两次gziping allready gzip压缩页面.有没有人知道一个更稳定的方法来使用ASP.NET MVC 2提供压缩页面,或者任何关于如何修改代码的想法更通用？

public class CompressFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(FilterExecutingContext filterContext)
    {
        HttpRequestBase request = filterContext.HttpContext.Request;
        string acceptEncoding = request.Headers["Accept-Encoding"];
        if (string.IsNullOrEmpty(acceptEncoding)) return;
        acceptEncoding = acceptEncoding.ToUpperInvariant();
        HttpResponseBase 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);
        }
    }

}

您可以忽略子操作:

if (filterContext.IsChildAction)
{
    return;
}
