Server Farm comes with three different operation modes.
Mode 1) Pass Through
In "Pass Through" mode all requests passes through the master HyperServer. This includes all file requests. Which means your master server can become quite busy when there is a momentary high load. In this mode each slave HyperServer instance communicates with its own Nodes privately. Slaves and related Nodes are isolated from the public access.
It is the slowest mode, but the easiest for uniGUI developers to implement, manage and maintain.
Mode 2) Direct
In this mode again all traffic is handled by the master HyperServer, but it will directly communicates with all Nodes from other HyperServer instances. This will improve performance, as the traffic are not relayed through the middle HyperServers.
Mode 3) Url Redirect
In this mode each new session is redirected to one of the slave HyperServers. It will be done at URL level, so once the session is redirected, the master HyperServer will not handle the related traffic. For each slave HyperServer Node the traffic is handled directly by that HyperServer.
This is the fastest operation mode, but this requires you to open all of your salves to the internet and assign them public URLs.
