The attached patch to the version of ldirectord in the heartbeat
CVS tree should enable ranges of virtual servers to be specified.
e.g.
virtual=192.168.6.240:80
real=192.168.6.2-192.168.6.30:80 gate
service=http
request="index.html"
receive="Test Page"
scheduler=rr
If there are no objections from Jacob I will commit this patch.
