Description |
I needed a regex for validating URLs, couldn't find a suitable one, so wrote this, with comments! It matches any valid web URL (Address or IP, with or without protocol), including optional port number, directory path, filname.extension and any paramater pairs. Hope it helps, even if just to understand expressions easier!
