關于haproxy會話保持

文檔上有寫haproxy具有會話保持功能，怎么保證的呢？
有人做過相關的測試嗎？

      source      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.

看文檔應該就是這個負載均衡算法選項可以完成session保持吧
