sticky

To ensure that connections from the same client that match the same SLB policy use the same real server on subsequent connections and enter the sticky submode, use the sticky command. To remove a sticky group, use the no form of this command.

Usage Guidelines Specifying a net mask permits sticky connections based on the masked client IP address.

Use the sticky time option to ensure that connections from the same client that match the same SLB policy use the same real server. If you specify a nonzero value, the last real server that was used for a connection from a client is remembered for the sticky-timevalue after the end of the client’s latest connection.

However, if the environment variable NO_TIMEOUT_IP_STICKY_ENTRIES is set to 1, then the sticky timer for a specific entry is reset from the point where the last session ends. This timeout policy applies to sessions using IP_Sticky only. Sessions using other forms of persistence (for example, cookie and url-hash) are not affected by this behavior.
