Thanks for your answer Nick,i still don't understand what mod_expires stand for, but anyway i solved my problem sending custom "no-cache" headers thanks to mod_headers, and i work like a charm :
Header set Expires "Thu, 01 Dec 2003 16:00:00 GMT" Header set Cache-Control "no-store, no-cache, must-revalidate" Header set Pragma "no-cache" Nick Kew a écrit :

That mechanism i correct in case i don't use mod_expires, but i want to invalidate cache as soon as the client gets the file.You can invalidate the cache as much as you like (I haven't checked your use of mod_expires). But that doesn't stop a browser using the cache if it's configured to do so. Your browser very sensibly checks with the server first.
