Instead of using the weights or doing round robin, a hash of the source IP is generated and this is used to find the correct real server. This means that the real server is always the same from the same host. You don't need any source IP persistence

If you limit a network, all hosts on the network count towards the limit, in the previous version each host would have separate limits

New Persist

This is the same as superHTTP BUT it also appends the source IP address to the string, thus improving the distribution of the resulting HASH.

HASH Function

The hash function for string persistency types (i.e. non sourceIP) has been improved, it will give a better distribution and fewer clashes

If you set a network and a host on that network, the host should be placed first since the list is processedin the order that it is displayed.
