squid dstdom_regex not working as expected

[Sachin Gupta <chingupt@xxxxxxxxx>]

Hi All,

I have configured a list of blacklist URLs.
One of these is set to (\.*)\.yahoo\.com

Now if i try to access URLs http://mail.yahoo.com from my browser, it blocks.
But if i try to access http://www.yahoo.com, it allows.

If i try to test the regular expression on
http://gskinner.com/RegExr/, it doestnt match.

Please guide.

Regards
