[MCCS]

i am trying to setup prestashop with an edgecast cdn,

simply enering the media servers would not work, because i have seen prestashop trying to fecth the CCC / (template/cache/987r839d3.js and .all_css files) from there.

is there a way to have prestashop get only the images externally and not the js and css
what would be the good way. i read also a code mod.

http://www.prestashop.com/forums/viewthread/57713/general_discussion/solved_is_it_possible_to_use_external_picture_links

but this is not a clean way to do it..also i saw in some older version configuration directives..

what is the right way? as there is no documentation can anyone please share what they got?

Thanks
