Web Agents and Dynamic Key Rollovers

You can use the Administrative UI to configure dynamic Agent key rollover. Web Agents poll the Policy Server for key updates at regular intervals. If keys have been updated, Web Agents pick up the changes during polling. The default polling time is 30 seconds, but you can customize it by changing the value of the PSPollInterval parameter for a Web Agent.

When a Web Agent detects that a key rollover has occurred, the Agent retrieves new values for the following Agent keys:

• Old Key

  Contains the last value used for the dynamic Agent key before the current value.

• Current Key

  Contains the value of the current dynamic Agent key.

• Future Key

  Contains the next value that will be used as the current key in a dynamic Agent key rollover.

• Static Key

  Contains a long-term key that the Agent can use for SiteMinder features that need to identify a user and maintain this information for long periods. Static keys also support cookie encryption for single sign-on when dynamic keys are not enabled.

Web Agents require multiple keys to preserve cookie data and ensure a smooth transition between old keys and new keys.
