How to compress javascript files from my rails application to apache / passenger?

Question

I am using Apache 2.2, Passenger 3.0.2, Rails 3.

I was able to compress the css file by changing the deflate.conf file. However, when I run firefox addon yslow, it still says javascript files are uncompressed.

<IfModule mod_deflate.c>
          AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/javascript text/javascript application/x-javascript
</IfModule>

Above, I use all three options: "application / javascript text / javascript application / x-javascript", but no luck.

Here is the message from yslow:

Level D on gzip compress components

There are 3 simple text components that need to be sent compressed.
