I've been searching numerous forums for the answer to this question because it seems like it'd be a common one. However, I think I'm so new I don't know what it is to look for, so I figured I'd just ask: I'm building a web-application in PHP that will call on remote URLS. Some will be GETs and others POSTs. I want to offer this as a free service, but only if I can build in an anonymous proxy so that my server IP isn't revealed. Can anyone give me any direction on how to do this? I've Google'd proxy scripts, and proxy for web-apps, but it seems like all the answers are for client side, not server-side proxies. Thanks in advance!
