This Regex:
^[a-z]+:// = at the start of the string find 1 or more letters, then a ://
(ie http://)
[a-z0-9:@&=;?%$.+!*'(),-]+ = after the above, find 1 or more of the
characters on the left
(/[a-z0-9:@&=;?##%$_.+!*'(),-]*)* = after the above, find 0 or more
/(characters)
It's not a wonderfully good regex imho. It will work, but will pass
through some useless info too.
Check google for URL validation regular expressions. This has been done
many times in Perl, so...
