I just started a proxy, http://www.instantunblock.com. I really don't want people looking at child porn using my proxy. Are there any proxies or scripts that let you view the websites your proxy visitors are viewing?
it should be very, very easy to modify that script to log what urls people go to. that being said: are you just assuming people are going to be using this to look at child porn, or has it actually happened? honestly, something as simple as "your IP is being logged by instantunblock.com, any illegal activities will be reported" or something would be enough to scare people off. blocking things page by page won't be easy, particularly if what you're referring to is "legal child porn" (... it's an MSNBC link. don't look at me like that.) then you may have a very very tough time blocking it because there's a lot of that out there.
I see what you mean. Of course I wouldn't actively look for every possibly illegal website being visited, but if I found a possibly illegal website being visited a bit too much, I would block the IP of the browser from the proxy. Do you know who could make me a script or can you point me out a resource for making one with PHP?
php.net is the ultimate resource. it's a bit intimidating when you're new, though. you can either just google for "PHP tutorials" or buy / go to the library and get a beginner's PHP book. may not be worth it for this task alone, but it'll be worth it in the long run if you run websites for a living (or hope to). as far as paying to get it done, there's the buy/sell forum here, scriptlance, etc.
