apache compression Deflate .js and .css files not compressed?


In Apache Im enabling output compression by adding the following to my .htaccess file:

# compress text, html, javascript, css, xml:
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

# Or, compress certain file types by extension:
<Files *.html>
SetOutputFilter DEFLATE
</Files>

So I'm serving all content with Content-Encoding: gzip but when I test my webpage with Yslow I receive:

Grade D on Compress components with gzip

There are 3 plain text components that should be sent compressed

* http://mysite.com/javascript/youTubeEmbed/youTubeEmbed-jquery-1.0.css
* http://mysite.com/javascript/jquery.swfobject.1-1-1.min.js
* http://mysite.com/javascript/youTubeEmbed/youTubeEmbed-jquery-1.0.js

Where's the problem?Shouldn't they get compressed automatically??

thanks

Solution

  • Did you remember to clear your cache before reloading the page and running Yslow?

    I had the exact same problem and fixed it like that. This is my code:

    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
