L4 server

This is the real server. All servers contained within the same farm deliver the same service.

Server attributes and options define the way and conditions by which to forward requests to the actual server, as well as its capacity to process requests comparatively to other servers of the same farm.

Servers are identified by a name and the name of the farm that it belongs to. Allowed characters are alpha-numerics, dot, dash, and underscore.

Hence, the higher the weight, the higher the load. The default weight is 1. The maximum value is 256. When using this parameter to distribute the load according to server capacity, it is recommended to start with values that can both grow and shrink, such as between 10 and 100 to leave enough room above and below for later adjustments.
