Dumb question, but does that proxy everything, set up that way, or only specified sites? Is there a way to have it only proxy some things? I'm concerned about cached copies of news pages and other things with rotating content.
When you use the PAC file on-campus, it configures the browser to send most requests out through the proxy.. Only the on-campus application servers bypass the proxy in that configuration.
News sites and the like shouldn't be an issue because the proxy respects the Expires and Cache-Control headers returned by the web servers. A site displaying dynamic content should be setting "Pragma: no-cache" (for HTTP 1.0 clients) and the "Cache-Control: no-store, no-cache, must-revalidate" (for HTTP 1.1 clients) headers.
