iRules, persistences, persistence profiles.

The easiest and most efficient way to ensure clients are persisted to the same pool member over the duration of a session is to use cookie insert persistence using the profile. This works well, is simple to configure and is more efficient than trying to mimic the functionality in an iRule.

 

 

The session commands add/retrieve/modify session table entries. On their own, no changes are made to pool member selection. It's just a way to store name - value pairs in the LTM memory. If you wanted to use the session table for persistence, you would need to explicitly select the pool member based on the session table entry or use the value as input for a persist command.

 

 

The persist commands allow you to add/retrieve/modify/use persistence table entries.
