Configure Response Attribute Caching

Responses return values to a requesting Agent. The data returned to the Agent can be a fixed value, or it may change over time. When you use a SiteMinder Agent to protect a resource, Agents can cache a value for fixed data, so that the value does not need to be recalculated each time the associated policy fires.

For example, a customer’s account number is a fixed value, while the customer’s account balance changes after each transaction. It would be more efficient to retrieve the account number once and then cache it. However, you probably want the balance to be recalculated at a regular interval to make sure the information is current.

Note: SiteMinder does not cache RADIUS response attributes.

Note: When you create or modify a Policy Server object in the Policy Server User Interface, use ASCII characters. Object creation or modification with non-ASCII characters is not supported.

To configure response attribute caching

1. In the SiteMinder Response Attribute Editor dialog, select one of the following radio buttons in the Attribute Caching region:

   Cache value

   Indicates the value of the response attribute should be calculated once and then cached for later use by the Policy Server. Use this radio button for attributes that remain static for extended periods of time.

   Recalculate value every <number> seconds

   Indicates the value of the response attribute should be recalculated at the interval of seconds that you enter in the field. Set this value to 1 second for information that should be recalculated each time the rule associated with the response fires.

   Note: Setting this interval to zero is equivalent to selecting the Cache Value radio button.

2. Click Apply to save your changes, or click OK to save your changes and return to the SiteMinder Administration window.
