Cache problem on web portal access F5 APM

hi!

on a web portal access, i need to cache nothing on the client side for security reasons. So in the rewrite engine, i put "no cache" and i added an irule (found on devcentral:-)) which add no cache, no store must revalidate if the content type contains "html".

My problem is when i look at googcle chrome cache, i saw documents even if the content-type is "text/html; charset=utf-8" and the cache-control on this html doc is "no-cache, must-revalidate".

Is there a better way to force to cache nothing when a client use chrome ??

thx for your help!
