使用gzip压缩组件的等级F

有19个纯文本组件应该压缩发送“

我已经使用“http://www.whatsmyip.org/http_compression/”单独检查了主页面的压缩以及所有19个组件,并且它显示了所有这些组件的压缩。此外,我确保我没有使用代理,并且“Accepting-Encoding”是使用“http://www.lagado.com/proxy-test”的gzip / deflate。与这些结果相反,mod_deflate日志文件如下(摘录):

  

...“GET / HTTP / 1.1”4498/13306(33%)   “GET /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“ - / - ( - %)   ...

所以它不压缩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,它现在有用了。我将修改后的配置文件设置如下

# 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>

然后浏览器缓存重新加载并检查日志文件并将其压缩。 Yslow同意了。
