This allows the lookup within ProxyTable to be a O(1) lookup on the routers object without RegExp. Instead of the O(n) RegExp based lookup that is currently in place.
This can be toggled by a boolean that can be passed to HttpProxy and ProxyTable.
Therefore for scenarios where you want a purely Host: header lookup this will be faster and will scale better when the proxy is infront of X'00 backends.
