Ultimately, no. You can block HTTPS altogether, but that's probably not feasible for various reasons. (Not least of which - many webmail providers now force HTTPS.) You might theoretically enforce the use of an HTTP proxy, and then theoretically limit CONNECT-style requests (which is how HTTPS works through a proxy) at a certain maximum size, but that will inevitably break many websites in seemingly-random ways because of HTTP Keep-alive which also functions in HTTP/S. This is the point of HTTPS, after all - completely opaque sessions from the browser all the way to the server, where you can't eavesdrop and you can't know what's going on in that connection. -Adam Thompson [email protected] _______________________________________________ List mailing list [email protected] http://lists.pfsense.org/mailman/listinfo/list
