I'm using assetic on Symfony 2 and I compress all my CSS and JS files thanks to YUI. ALL works perfectly, but on prod environment, I have multiple calls to load every compressed files. In fact, I thought that assetic could combine all CSS files (and JS files) to have just a single call to a unique file (one for CSS, another one for JS), and that for each page, is it possible ?

I don't find documentation about it ...
Have an idea ?
Thanks !
