HTTP cache headers with .htaccess

I am trying to configure my .htaccess file to set the cache time. Tried every possible configuration but nothing works!

This is what is written in my HTML:

<meta http-equiv="Cache-Control" content="max-age=2592000, public" />
<!-- <meta http-equiv="expires" content="mon, 24 sep 2012 14:30:00 GMT"> -->

and this is what written in my .htaccess file:

ExpiresActive On
ExpiresDefault A3600

However, when I refresh including cache clear (ctrl+F5) in firefox, my firebug NET panel says that the cache expires at the same second I have accessed the file (and not in the future, as I want it to be).

What am I doing wrong??

Thanks

I advise you to use headers mod. You can activate it (if disabled) with this command :

a2enmod headers

Here is a simple code example that works:

<IfModule mod_headers.c>
    # WEEK
    <FilesMatch "\.(jpg|jpeg|png|gif|swf)$">
        Header set Cache-Control "max-age=604800, public"
    </FilesMatch>

    # WEEK
    <FilesMatch "\.(js|css|swf)$">
        Header set Cache-Control "max-age=604800"
    </FilesMatch>
</IfModule>

max-age is cached time in seconds.
