Hi,
I looked around the source code and made some modifications to fit my needs.
With this patch,
server=/.google./127.0.0.1#5053 # match domains with .google. in it or
ending with .google
#server=/.google/127.0.0.1#5053 # ditto
server=/.google.co./127.0.0.1#5053 # the same as server=/.
google.co/127.0.0.1#5053
server=/.google.com/127.0.0.1#5053 # the same as server=/.google.com./
127.0.0.1#5053
.google.com.hk will match the /.google.com/, and .google.co.hk will match
the /.google.co./
Regards,
hmj
