“使用 gzip 压缩组件的等级为 F

有 19 个纯文本组件应该被压缩发送”

我已经检查了主页的压缩情况，以及使用“http://www.whatsmyip.org/http_compression/" 并且它显示了所有压缩。此外，我确保我没有使用代理，并且“Accepting-Encoding”是 gzip/deflate 使用“ http://www.lagado.com/proxy-test”。与这些结果相反，mod_deflate 日志文件如下（摘录）：

...“GET / HTTP/1.1”4498/13306 (33%) “获取/Home_Page/style.css HTTP/1.1” -/- (-%) "GET /css/style.css HTTP/1.1" -/- (-%) "GET /css/slimbox.css HTTP/1.1" -/- (-%) "GET /js/validator_o.js HTTP/1.1" -/- (-%) ...

所以它没有压缩css或js文件？我的配置文件如下：

<IfModule mod_deflate.c>    SetOutputFilter DEFLATE

AddOutputFilterByType DEFLATE text/html text/plain text/css text/javascript text/xml image/svg+xml application/javascript application/x-javascript application/atom_xml application/rss+xml application/xml application/xhtml+xml application/x-httpd-php application/x-httpd-fastphp

没关系，现在它起作用了。我按如下方式设置修改后的配置文件，

# Method 2: Compress all content, manually excluding specified file types
<IfModule mod_deflate.c>
  # place filter 'DEFLATE' on all outgoing content
  SetOutputFilter DEFLATE
  # exclude uncompressible content via file type
  SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|rar|zip)$ no-gzip
  <IfModule mod_headers.c>
    # properly handle requests coming from behind proxies
    Header append Vary User-Agent
  </IfModule>
</IfModule>

然后重新加载浏览器缓存并检查日志文件，它已被压缩。伊斯洛同意了。
