Question

我无法尝试为我正在处理的（gzip asp.net）网站启用webforms压缩功能。我认为我已经完成了所有工作，但是当我动态加载webresource.axd和scriptresource.axd文件时，它们会被压缩，因此页面无法加载依赖于上述文件的内容或（在调试时）打破了无数的javascript运行时异常，即;无效的角色。

这是我的Global.ascx.cs代码的一部分，显然是连接到PostReleaseRequestState事件。

void OnGlobalPostReleaseRequestState(object sender, EventArgs e)
{    
        string contentType = Response.ContentType;

        // Compress only html, style-sheet, and javascript documents.
        switch (contentType)
        {
            case "application/x-javascript":
            case "text/javascript":
            case "text/css":
            case "text/html":
                {
                    // Get the Accept-Encoding header value to know whether zipping is supported by the browser or not.
                    string acceptEncoding = Request.Headers["Accept-Encoding"];
                    if (string.IsNullOrEmpty(acceptEncoding)) return;

                    // If gzip is supported then gzip it else if deflate compression is supported then compress in that technique.
                    if (acceptEncoding.Contains("gzip"))
                    {
                        // Compress and set Content-Encoding header for the browser to indicate that the document is zipped.
                        Response.Filter = new GZipStream(Response.Filter, CompressionMode.Compress);
                        Response.AppendHeader("Content-Encoding", "gzip");
                    }
                    else if (acceptEncoding.Contains("deflate"))
                    {
                        // Compress and set Content-Encoding header for the browser to indicate that the document is zipped.
                        Response.Filter = new DeflateStream(Response.Filter, CompressionMode.Compress);
                        Response.AppendHeader("Content-Encoding", "deflate");
                    }
                }
                break;
        }
    }

我的web.config包含相关部分。

我需要禁用（* .axd）压缩，或者强制它在客户端上解压缩。请帮忙......

好的，所以我想出了我的问题的答案......显然是问我需要做的全部问题，自己回答。首先，IE在确定缓存动态（* .axd）文件方面很糟糕，因此我只需要清除IE的缓存（和历史记录）并对请求添加一个简单的检查，如下所示。

void OnGlobalPostReleaseRequestState(object sender, EventArgs e)
{
    if (Request.RawUrl.Contains("ScriptResource.axd", StringComparison.OrdinalIgnoreCase))
    {
        return;
    }

    string contentType = Response.ContentType;

    // Compress only html, style-sheet, and javascript documents.
    switch (contentType)
    {
        case "application/x-javascript":
        case "text/javascript":
        case "text/css":
        case "text/html":
            {
                // Get the Accept-Encoding header value to know whether zipping is supported by the browser or not.
                string acceptEncoding = Request.Headers["Accept-Encoding"];
                if (string.IsNullOrEmpty(acceptEncoding)) return;

                // If gzip is supported then gzip it else if deflate compression is supported then compress in that technique.
                if (acceptEncoding.Contains("gzip"))
                {
                    // Compress and set Content-Encoding header for the browser to indicate that the document is zipped.
                    Response.Filter = new GZipStream(Response.Filter, CompressionMode.Compress);
                    Response.AppendHeader("Content-Encoding", "gzip");
                }
                else if (acceptEncoding.Contains("deflate"))
                {
                    // Compress and set Content-Encoding header for the browser to indicate that the document is zipped.
                    Response.Filter = new DeflateStream(Response.Filter, CompressionMode.Compress);
                    Response.AppendHeader("Content-Encoding", "deflate");
                }
            }
            break;
    }
}

详细here - ScriptResource.axd会自动压缩，知道这一点后，我现在可以过滤掉包含scriptresource.axd作为原始网址一部分的所有请求。

使用fiddler我能够看到（ScriptResource.axd）文件在其标题中有两个“内容编码”的“gzip”，一个是自动发生的，另一个是我追加的。 / p>

双重压缩==主要问题！：）

ASP.NET，GZip和.AXD动态文件打得不好
