当我使用压缩过滤器并获得错误时,错误页面只是乱码字符.问题似乎是当IIS转移到错误页面时,压缩过滤器仍然有效,但标题被清除.如果没有"Content-encoding:gzip"标头,浏览器只会显示原始gzip二进制数据.

我正在使用IIS7.5,ASP.NET MVC 2 Preview 2和一个看起来像这样的ActionFilter:

public class CompressResponseAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var request = filterContext.HttpContext.Request;
        var response = filterContext.HttpContext.Response;

        var acceptEncoding = request.Headers["Accept-Encoding"];

        if (string.IsNullOrEmpty(acceptEncoding))
            return;

        acceptEncoding = acceptEncoding.ToLowerInvariant();

        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);
        }
    }
}

有人经历过这个吗？
