我有这个添加到我的.htaccess：

<IfModule mod_headers.c> 
    Header unset ETag 
    Header unset Last-Modified 
</IfModule> 
FileETag None 

<IfModule mod_deflate.c> 
    AddOutputFilterByType DEFLATE text/plain 
    AddOutputFilterByType DEFLATE text/html 
    AddOutputFilterByType DEFLATE text/xml 
    AddOutputFilterByType DEFLATE text/css 
    AddOutputFilterByType DEFLATE application/xml 
    AddOutputFilterByType DEFLATE application/xhtml+xml 
    AddOutputFilterByType DEFLATE application/rss+xml 
    AddOutputFilterByType DEFLATE application/javascript 
    AddOutputFilterByType DEFLATE application/x-javascript 
    BrowserMatch ^Mozilla/4 gzip-only-text/html 
    BrowserMatch ^Mozilla/4\.0[678] no-gzip 
    BrowserMatch \bMSIE !no-gzip !gzip-only-text/html 
    SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary 
    Header append Vary User-Agent env=!dont-vary 
</IfModule> 

<Files *.php> 
    SetOutputFilter DEFLATE 
</Files> 

<IfModule mod_gzip.c> 
    mod_gzip_on Yes 
    mod_gzip_dechunk Yes 
    mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$ 
    mod_gzip_item_include handler ^cgi-script$ 
    mod_gzip_item_include mime ^text/.* 
    mod_gzip_item_include mime ^application/x-javascript.* 
    mod_gzip_item_exclude mime ^image/.* 
    mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* 
</IfModule> 

<IfModule mod_expires.c> 
    ExpiresActive On 
    ExpiresDefault "access plus 1 seconds" 
    ExpiresByType text/html "access plus 1 seconds" 
    ExpiresByType image/gif "access plus 2592000 seconds" 
    ExpiresByType image/jpeg "access plus 2592000 seconds" 
    ExpiresByType image/png "access plus 2592000 seconds" 
    ExpiresByType text/css "access plus 604800 seconds" 
    ExpiresByType text/javascript "access plus 216000 seconds" 
    ExpiresByType application/x-javascript "access plus 216000 seconds" 
</IfModule>

调整需要什么，以避免上述报告进行？

注：这是由ExpresssionEngine不带扩展名担任模板链接：

http://www.mysite.com/css/c/style 
http://www.mysite.com/j/banner_slides 
http://www.mysite.com/j/multi-click-slider

ExpressionEngine GZIP输出设置为Yes。

确保你做了页面的硬刷新（ctrl + F5）。我注意到YSlow使用缓存的标题信息，因此没有显示正确的信息。

此外，请确保您已启用适当的Apache模块。通过删除ifmodule标签（除了mod_gzip标签，您可以完全删除的部分）来检查。

我认为YSlow要求至少有7天到期，至少604800秒。

也删除行：Header unset Last-Modified除非你知道它做了什么，并有一个特殊的目的。

YSlow必须每次都使用相同的缓存，因为我已经这样做了，它仍然会提供相同的信息。它可能是过期和gzip没有启用我的服务器？ – MB34 2012-02-20 16:47:15

只需检查HTTP标头，看看是否存在'Expires：...'和/或'Content-Encoding：gzip' – Gerben 2012-02-20 17:02:19
