Login to the OpenSSO Enterprise Console as amadmin.
Click Access Control, realm-name, Agents, Web, and then the name of the agent you want to configure.
Click Advanced, and then Sun Java System Web Server.
For POST Data Preservation, check Enabled.
For POST Data Entries Cache Period, specify a value in minutes, if you want a value other than the default value of 10.
This value determines the time in minutes that POST data is valid in the Web Server 7.0 cache.
These values are hot-swappable, which means you don't have to restart Web Server 7.0 after you set them. Any changes done in the Console are not reflected in the agent's local configuration file (and vice versa).
