patch-realserver-support
- added optional realserverip variable to config.xml which will allow direct checking of named vhosts on multiple realservers behind a loadbalancer.
- use <realserverip>x.x.x.x</realserverip> in the config.xml and the host part of the url listed in each test case will be replaced with this ip address, while still sending the host (fqdn) in the http host header
