Yes, mstshash contains the user name, which can only be used as a load balancing method. If the size of the server farm changes (eg: change in weight or in number of servers UP), the load balancing will change. The msts cookie contains the server's IP address, which can be used as a persistence method, whatever the number of servers, because haproxy is able to spot the correct server based on the cookie.
