2: Configuration level

In an HTTP server cluster, different referers correspond to different real servers. Load balancing is based on the referers.

For referer-based SLB:

When an HTTP request packet matches a sticky session entry, the packet is distributed based on the entry.
When selecting a new real server for load balancing, select the real server associated with the HTTP requested referer.
