Allow users to have multiple rdp sessions?


#1

Testing haproxy as a load balancing tool to our 4 2008 R2 terminal servers.

It’s working ok except that I can’t work out how to let staff have more than one simultaneous rdp session. At present if they start a second rdp session from a different device haproxy always connects them to their existing session. I can understand why this is happening as the hash is seeing the user name but I’d like users to be allowed 2 different rdp server sessions simultaneously.

Does anyone know how to acheive this with ha proxy?

Many thanks,

Greg.

Can you post your haproxy.cfg file ?
