Qlik Sense supports network load balancers (NLB) for distributing user sessions over multiple Qlik Sense Proxies.
A successful load balancing setup requires that the NLB complies with Qlik Sense basic requirements for communication;
- Open ports
- Support for WebSocket protocol
- Sticky/persistent sessions
- Session timeout
Qlik Sense does deem specific networks load balancers supported or not supported, but requires that load balancers behavior comply with the Qlik Sense traffic requirements.
