How to exclude some CSS or JS files from CCC (Cache concatenation and compression)

[vcopleutre]

Hi everyone,

In order to increase the loading time on my site I want to delay some CSS/JS calls to improve my critical path.

To limit the parallel downloads, my CCC is activated.

My question is : How to exclude some CSS and JS files from being included in CCC ? 

I'd like to have on constant CCC file (which includes like global.css, product_files.css, etc... main css files) and other CSS files which would be called depends on the page. It would greatly increase the rendering speed of my site.

Any ideas ? thx
