sej: The Safari UI itself isn't GPL; KHTML is LGPL, so it doesn't require Safari to be GPL. Trust me, if Apple were violating the GPL, KDE would've noticed a long, long time ago, and made a lot of noise. They've fed back all of their KHTML changes to us; probably the best-changelogged patchset we've ever had. ;)

mglazer: This idea is still stupid. You're running PHP, which means that I can sit there requesting all the pages I like; it may not give me the page proper, but you're still running the PHP, hitting the database, all of that. Either way, you lose. Besides, your approach would kill any busy proxy. Face it, PHP won't prevent DDoS.

Even though the bushfires are quite far away, the CBD here is shrouded in smog, and you can smell the smoke, it's quite thick in the air.
