session persistence ? why it is required

Hello GLM,

 

According to F5,

 

The primary reason for tracking and storing session data is to ensure that client requests are >directed to the same pool member throughout the life of a session or during subsequent sessions.

 

Long story short, this can save end-user preferences, session information, authentication info, etc. If you want more info, you can read this page here.

 

Have fun,

 

Austin
