我特林實現什麼史蒂夫Souders的討論http://www.stevesouders.com/blog/2010/07/12/velocity-forcing-gzip-compression/有關強制gzip壓縮我試圖強制使用GZipStream在頁面上gzip壓縮,但瀏覽器說我使用不支持壓縮

我有一個模塊的運行這樣的:

void context_PreSendRequestHeaders(object sender, EventArgs e) 
{ 
    var app = sender as HttpApplication; 

    var request = app.Request; 
    var response = app.Response; 

    if (CompressionUtils.GzipSupported(request) || CompressionUtils.GzipNotSupportedExplicitly(request)) 
    { 
     return; 
    } 

    if (CompressionUtils.GzipSupportedExplicitly(request)) 
    { 
     response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); 
     response.AddHeader(HttpHeaderKey.ContentEncoding, "gzip"); 
     return; 
    } 

    response.Write("<iframe style=\"display:none;\" src=\"/CompressedPage.aspx\"></iframe>"); 
} 

CompressionUtils.GzipSupported只檢查了「編碼接受 - 」標題,而 CompressionUtils.GzipSupportedExplicitlyCompressionUtils.GzipNotSupportedExplicitly檢查的cookie說瀏覽器是否真的能夠讀取gzip的

但是,當我在Firefox加載頁面我得到這個錯誤:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

和提琴手它表明content-encoding頭已被添加,但內容沒有被壓縮

所以原來我只是綁定太晚了,綁定到PostMapRequestHandler而不是PreSendRequestHeaders。現在工作正常。
