Allocate Traffic to Servers by	Defines how likely it is that traffic is redirected to a particular server. Usually it is best to select the least granular option that still produces an acceptable distribution of traffic. The options are (from least granular to most granular): Not Defined — Not Defined has the same effect as the Source Network option. Source Network — Directs traffic coming from the same C-class network to the same server. This option is a good choice when connections come from many different networks. Host — Directs traffic coming from the same IP address to the same server. This option is a good choice when a large portion of connections come from different hosts in the same C-class network. Connection — Makes a new traffic management decision for each new connection. This choice might be necessary if a large portion of connections uses just one IP address. Order — Allocates traffic based on the order of the elements on the list.
