Have UrlAttribute not require input #50

Closed scottksmith95 closed 12 years ago

I have a case where I want to validate input to make sure it is a valid Url, but if nothing is entered, I want it to pass validation.

This is the default behavior-- an empty URL should pass validation (additionally, an empty field should pass any validation other than "required"). Make sure you don't also have [Required] on the field (look for the required or data-val-required attributes on the input box)
