^(((ht|f)tp(s?))\://)?(www.|[a-zA-Z].)[a-zA-Z0-9\-\.]+\.(com|edu|gov|mil|net|org|biz|info|name|museum|us|ca|uk)(\:[0-9]+)*(/($|[a-zA-Z0-9\.\,\;\?\'\\\+&%\$#\=~_\-]+))*$ |
| Description |
Version 1.3.0: I needed a regexp to validate URL's without the ht(f)tp(s):// and include North American domains (like .us and .ca) and there didn't seem to be one available...so I created one. It will also work with ASP QueryStrings and anchor URL's. If you have a problem with the expression or have any suggestions to improve, please write me and let me know. Added .uk domain and expression now allows for URLs that contain JSP session IDs. 4/14/04 - added ability to include URLs that start with server names. |
