Chapter 2 Content Switching Module with SSL Commands

sticky (virtual server submode)

sticky (virtual server submode)

To ensure that connections from the client use the same real server, use the sticky command in the virtual server submode. To change the sticky timer to its default value and remove the sticky option from the virtual server, use the no form of this command.

Usage Guidelines

 

Sticky connections are not tracked. The group ID default is 0. The sticky feature is not used for other

 

 

virtual servers. The network default is 255.255.255.255.

The last real server that was used for a connection from a client is stored for the duration value after the end of the client’s latest connection. If a new connection from the client to the virtual server is initiated during that time, the same real server that was used for the previous connection is chosen for the new connection.

A nonzero sticky group ID must correspond to a sticky group previously created using the sticky command. Virtual servers in the same sticky group share sticky state information.
