It "intercepts" requests and acts as them just like a normal proxy, but it usually invisible to the end user's Internet experience. It is done in conjunction with a firewall or TCP proxy capable of redirecting the object request to the cache. Example: Bob runs the IT department for a fortune 500 company consisting of 20k users. Rather than administer the proxy settings of everyone's workstations, they implement a series of transparent proxies to work "behind the scenes". Centralizes administration nicely. > >If you put one of those "expired" meta tags in the header of the web page, > >will that force the proxy to refresh it's cache each time the page is > >requested? > > Good question.

Squid, for example, will allow you to ignore the meta expire via the override-expire directive. Of course, this breaks the HTTP standard and should be done at your own risk. -- Jason Dixon, RHCE DixonGroup Consulting http://www.dixongroup.net -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
