Hi, i'm using squid as an accelarator for Plone, a CMS built on Zope.
On the xhtml content i set the Cache-control header as must-revalidate,max-age=0,s-maxage=36000. The browser will always check back for changes, squid will get a purge request if something changes. This breaks as soon as some transparent proxy gets in the way that picks up the s-maxage header. So i'd like to strip any s-maxage headers or set them to 0 when passing through squid. I took a look at header_access and header_replace: header_access Cache-control deny all header_replace Cache-control Must-revalidate,max-age=0,s-maxage=0 This makes the browser check back for everything on every request (stylesheets, pics...), very slow. What i'd like to achieve is a conditional replace only if s-maxage was included in the original header. Is this possible with some acl matching magic? Thanks for any ideas! Gabriel
