title: YSlow tells me site is not compressed even though it is
body: <p>"Grade F on Compress components with gzip</p>
  
  <p>There are 19 plain text components that should be sent compressed"</p>
  
  <p>I have checked the compression of the main page, as well as all 19 components individually using "<a href="http://www.whatsmyip.org/http_compression/" rel="nofollow noreferrer">http://www.whatsmyip.org/http_compression/</a>" and it shows compression in all of them. Furthermore, I ensured I'm not using a proxy and that "Accepting-Encoding" is gzip/deflate using "<a href="http://www.lagado.com/proxy-test" rel="nofollow noreferrer">http://www.lagado.com/proxy-test</a>". Contrary to these results, the mod_deflate log files is as follows (excerpt):</p>
  
  <blockquote>
    <p>... "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" -/- (-%)
    ...</p>
  </blockquote>
  
  <p>So it's not compressing the css or js files? My config file is as follows:</p>
  
  <pre><code>&lt;IfModule mod_deflate.c&gt;    SetOutputFilter DEFLATE
