------------------------------------
Github user sdutry commented on the issue:
https://github.com/apache/struts/pull/157
> After the commit above, any IP with 3 digits in the last octet will not
pass validation
You are right, i forgot the grouping (meaning the or statements mean
something completely different), i'll fix this ASAP
> The expression did not seem to work at all until I escaped the slashes,
changing / to \/
I don't see why this would be. I am not aware that a "/" is a special sign
inside a java string or java RegEx. Or is it because this same regex is used in
javascript regex validation (where the '/' sign does mean something). I'll
change it back ASAP too
> Improve RegEx used to validate URLs
