		 			  The source IP address is hashed and divided by the total
	                  weight of the running servers to designate which server will
	                  receive the request. This ensures that the same client IP
	                  address will always reach the same server as long as no
	                  server goes down or up. If the hash result changes due to the
	                  number of running servers changing, many clients will be
					  directed to a different server. This algorithm is generally
	                  used in TCP mode where no cookie may be inserted. It may also
	                  be used on the Internet to provide a best-effort stickyness
	                  to clients which refuse session cookies. This algorithm is
	                  static, which means that changing a server's weight on the
	                  fly will have no effect.
