<div>I'm really talking about optimizing about 3000 url regexes

<div>I know using
(www\.facebook\.com)|(facebook\.com)|(www\.google\.com)|(google\.com)
with PCRE will produce the same optimized result as
(www\.)?(facebook|google)\.com. Squid uses GnuRegex. Does
GNURegex lib optimizes this as well ?</div>
