URL hashing for server load balancing

By enabling URL hashing, requests going to the same page of an origin server are redirected to the same real server or cache server.

WSM SLB hashes, by default, on the IP source address and/or IP destination address (depending on the application area) to determine content location. The WSM may not send Web requests for the same origin server to the same proxy cache server. For example, different clients requesting
http://www.nortelnetworks.com/products may be sent to different caches.

You can direct the same URL request to the same cache or proxy server by using a virtual server IP address to load balance proxy requests. By configuring the hash or minmisses SLB metric, the WSM uses the number of bytes in the URI to calculate the hash key. If the host field exists and the WSM is configured to look into the Host: header, it calculate the hash key based on the Host: header field.
