Modern TLS versions and cipher support
Certificate import, renewal, and expiration monitoring
TLS re-encryption to backend services when required
|
| 06Session Persistence & Connection Management |
Keeps related requests connected to the appropriate backend when applications require session affinity or persistent client connections. |
Receive Initial Client Request→
Select Backend Server→
Create Persistence Rule→
Route Related Requests Consistently
|
Cookie, source-IP, or application-based persistence
Configurable persistence duration and failover behavior
Connection pooling, timeout, and keep-alive controls
