If so, is there some way I can block them (if they aren't already being blocked) without completely disabling http access? My server should not be acting as a proxy for anyone.
Also, I should have mentioned in the original post that not all the requests are for pages on banners.webmasterplan.com--that was just the one I happened to copy/paste. The pages that are being requesting (and generating all the errors) are on tons of different servers, none of which have anything to do with my server.
Sorry my questions may be a little unintelligent my networking skills are a little rusty.
Thanks for the help,
