+				suited for protocols using short sessions such as HTTP. This
+				algorithm is dynamic, which means that server weights may be

+		 			  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.
