Explanation/Reference:
Explanation:
URL hashing is a load-balancing predictor for Layer 7 connections. You can configure URL hashing on the CSM on a server farm-by-server farm basis. The CSM chooses the real server by using a hash value based on a URL. This hash value may be computed on the entire URL or on a portion of it. To select only a portion of the URL for hashing, you can specify the beginning and ending patterns in the URL so that only the portion of the URL from the specified beginning pattern through the specified ending pattern is hashed.
