Web pages usually consist of many resources, all of which are potentially protected by the Web Agent. For each resource associated with a single request, a session (SMSESSION) cookie is generated by default. When the Agent generates multiple session cookies for a single user request, this action causes overhead. To eliminate the overhead, set the following parameter:
Specifies the number of seconds the agent waits from the last accessed time of the received session cookie before it generates a new session cookie. Set the SessionGracePeriod to 0 to disable the setting. If the setting is disabled, the agent updates session cookies for every request instead of skipping updates.
There are times in which the session cookie will still be updated within the Session Grace Period calculation. Specifically any time the Web Agent has to make a request to the Policy Server.
