How can I make Squid to ask to my webserver if a content has the same ETAG everytime the content is requested? I have Squid in front of a Plone. When a user checks a web as anonymous and then logs-in and checks the same page, keeps seen it as Anonymous; but If the user refresh the site then can see it as logged. The ETAGs are diferent for an anonymous and for a logged user. Any idea how to solve that? Thanks, Daniel
