Add http(s) to URL if it's not there?

I wouldn't try to do that in the validation, since it's not really part of the validation.

Have the validation optionally check for it; if they screw it up it'll be a validation error, which is good.

Consider using a callback (after_create, after_validation, whatever) to prepend a protocol if there isn't one there already.
