HA Failover without session drops/failures

Available in version 13

In BIG-IP 12.0.0 and later, you can configure the system to mirror Secure Socket Layer (SSL) connections that are terminated by the BIG-IP system to peer device group members. When you enable connection mirroring on a virtual server that references an SSL profile, the BIG-IP system mirrors SSL-specific data to the appropriate device group member. This preserves SSL connections when failover occurs.

The following configuration options are not supported for virtual servers configured to mirror SSL connections: •HTTP profiles (12.0.0 - 12.1.2)* •Server SSL profiles (12.0.0 - 12.1.2)* •UDP profiles •iRules (12.0.0 - 12.1.2)* •Other L7 features

*Support for these configuration options is introduced in BIG-IP 13.0.0.
