Comment:
Better version of this. in backreference goes preceselly protocol, username, password, hostname and port. As well faster since doesn't use backtracing:
^(?:(http|https|ftp):\/\/)?(?:([^:]+):([^@]+)@)?((?:[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])(?:(?:\.[a-zA-Z0-9][a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])*))(?::([0-9]{1,5}))?((\/.*?)(\?(.*?))?(\#(.*))?)?$
