Web Gateway requires an external
Description
The GSLB functionality can be part of the DNS server and not
the load balancer. In this case, however, the DNS server must
be able to route requests to different locations based on the
location of the browser that initiated the request.
• Session affinity is based on cookies.
• The reverse proxy inserts a cookie to responses for incoming
HTTP requests and routes subsequent requests that contain
the same cookie to the same Avaya Aura
server.
• This feature is also known as sticky sessions. Do not use IP-
based sticky sessions because this might affect load
balancing.
• The load balancer must not block web socket requests and
must relay the web socket connections between the client
and the server.
• HTTP request timeout must be configurable. You must be
able to configure the timeout value to the maximum duration
of the conference to prevent it from timing out the web
socket session.
The load balancer must be able to route requests to different
backends based on the request URL.
