I never used l7vsadm but there is nowhere written that the matching 
string operates only on the path portion of the URL.

Have you tried e.g.

l7vsadm -a -t 192.168.8.58:80 -m url --pattern-match 'domain2.com*' -r 
10.0.0.10:80
or
l7vsadm -a -t 192.168.8.58:80 -m url --pattern-match '*domain2.com*' -r 
10.0.0.10:80

Best Regards,

Volker
