    Access Type read-write
    Restart Required all-services
  • disable-caching-for-secured-pages If Undertow should set headers to disable caching for secured paged. Disabling this can cause security problems, as sensitive pages may be cached by an intermediary.

This number refers to the number of bytes of randomness that are used to generate the session ID, the actual ID that is sent to the client will be base64 encoded so will be approximately 33% larger (e.g. a session id length of 30 will result in a cookie value of length 40).
