Not sure what else you need. Code is sample code supposed create caching headers to lessen HTTP server load. Server is Apache2 on localhost, Browser is IE6. After loading the page, then clicking 'reload' the issue appears. The problem only appears with direct connection, when going why proxy it doesn't happen.
