Espen Amble Kolstad commented on NUTCH-505:
-------------------------------------------

Automaton (http://www.brics.dk/automaton/), used in AutomatonURLFilter, is even faster if
you preparse the regex'es
It doesn't support all regex, but most.

> Parse plugins may extract garbage urls from pages. We need a url validation system that
tests these urls and filters out garbage.
