Answer 1

^(http|https):\/\/|[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,6}(:[0-9]{1,5})?(\/.*)?$/ix

• example.com
• sub.example.com
• sub.domain.my-example.com
• example.com/?stuff=true
• example.com:5000/?stuff=true
• sub.domain.my-example.com/path/to/file/hello.html
• hello.museum
• http://railsgirls.com

http://rubular.com/r/cdkLxAkTbk

Added optional http:// or https://

The longest TLD is .museum, which has 6 characters...
