Session cache configuration overview
A session cache allows a server to store session information from multiple clients. WebSEAL uses two types of session caches to accommodate both HTTPS and HTTP session state information between clients and WebSEAL:
- WebSEAL session cache
The WebSEAL session cache stores information about all sessions established by authenticated and unauthenticated users. The session key, stored with the client, is a locator index to the associated session data stored in the WebSEAL session cache.
The WebSEAL session cache stores, among other data, the credential information obtained for each client. Credential information is cached to eliminate repetitive queries to the user registry database during authorization checks.
- SSL session ID cache
The SSL session cache stores the SSL session ID used to maintain SSL session state.
SSL session IDs can be used as the session index for the WebSEAL session cache.
Configuration file entries
for configuring the WebSEAL session
cache and the SSL session ID cache are summarized in the following diagram:
