 |`RELOAD_SCRIPT` |  | The path to the reload script to use to reload the router.
 |`ROUTER_ALLOWED_DOMAINS` | | A comma-separated list of domains that the host name in a route can only be part of. Any subdomain in the domain can be used. Option `ROUTER_DENIED_DOMAINS` overrides any values given in this option. If set, everything outside of the allowed domains will be rejected.
 |`ROUTER_BACKEND_CHECK_INTERVAL` | 5000ms | Length of time between subsequent "liveness" checks on backends. xref:time-units[(TimeUnits)]
+|`ROUTER_BACKEND_PROCESS_ENDPOINTS` | | String to specify how the endpoints should be processed while using the template function processEndpointsForAlias. Valid values are ["shuffle", ""]. "shuffle" will randomize the elements upon every call. Default behavior returns in pre-determined order.
 |`ROUTER_CLIENT_FIN_TIMEOUT` | 1s | Controls the TCP FIN timeout period for the client connecting to the route. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection anyway.  This is harmless if set to a low value and uses fewer resources on the router.  xref:time-units[(TimeUnits)]
 |`ROUTER_COOKIE_NAME` |  | Specifies cookie name to override the internally generated default name.  The name must consist of any combination of upper and lower case letters, digits, "_",
 and "-". The default is the hashed internal key name for the route.
