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

Question

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

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
