Error with URL RegEx #210

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago

There is a bug in the Validator URL RegEx

Validator.URL=^(ht|f)tp(s?)\\:\\/\\/[0-9a-zA-Z]([-.\\w]*[0-9a-zA-Z])*(:(0-9)*)*(
\\/?)([a-zA-Z0-9\\-\\.\\?\\,\\:\\'\\/\\\\\\+=&amp;%\\$#_]*)?$

I guess this should be "(:(0-9){1,5})?" and not "(:(0-9)*)*" since
you don't want URLs with multiple ports, do you? ;-)

Even with that new validation, it is possible to create an url like following, 
and be validated:

http://www.something.com:80808080/text

the reason is that when the matching on the : with the numbers fail, it 
continues to the next part where : and numbers are allowed.
