some http proxy service providers here just assigned an unique proxy address and port to a user, and the user just need to enter the necessary proxy address and port to get access.I think this method is superior to username and password authentication, and also,this makes it possible to proxy a lot of mobile apps on ios devices and android which don't support traditional proxy authentication. i found they are using squid for caching and proxying. can squid alone achieve this?
