I need to improve my leverage browser caching.  I have this exact code in my htaccess file but it does not seem to be effective.  Plus, I see this code written differently all over the web.  Ie. some have # in front and some don't. Others use different coding, etc...

How exactly should my code look like.  See below.

<IfModule mod_expires.c>
  #ExpiresActive On
  #ExpiresByType image/gif "now plus 9 years"
  #ExpiresByType image/jpg "now plus 9 years"
  #ExpiresByType image/png "now plus 9 years"
  #ExpiresByType image/x-icon "now plus 9 years"
  #ExpiresByType text/html "now plus 9 days"
  #ExpiresByType text/txt "now plus 9 days"
  #ExpiresByType text/css "now plus 20 days"
  #ExpiresByType text/js "now plus 9 years"
  #ExpiresByType image/ico "now plus 30 days"
  #ExpiresByType application/javascript "now plus 2 weeks"
  #ExpiresByType application/x-javascript "now plus 2 weeks"
</IfModule>

The '#' in the first column makes it a 'comment', not a command.  Here's the manual page from Apache:  http://httpd.apache.org/docs/2.2/mod/mod_expires.html

Note that even without the comment tags, those directives have no effect on items already in the browser cache because that info is only passed when the file is delivered from the server.

There is also a sentence in the fourth paragraph on that page that says those directives will not replace any commands that are already present in the response.

And last, those commands do not over-ride what the user has set in their browser.  If they set their cache to expire in 3 days, that's what will happen.
