    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • allow-orphan-session Indicates whether session creation should be permitted after a response-closing operation, e.g. HttpServletResponse.sendRedirect(...). Enabling this behavior is generally discouraged, as the created session will be unreferenceable.
    • Attribute Value
    Default Value false
    Type BOOLEAN
    Nillable true

    • Attribute Value
    Default Value default
    Type STRING
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • default-cookie-version The default cookie version servlet applications will send
  • default-encoding Default encoding to use for all deployed applications
    • Attribute Value
    Type STRING
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • default-session-timeout The default session timeout (in minutes) for all applications deployed in the container.

    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • 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.

    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services

  • disable-session-id-reuse If this is true then an unknown session ID will never be reused, and a new session id will be generated.

    • Attribute Value
    Default Value false

    • Attribute Value
    Type INT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • ignore-flush Ignore flushes on the servlet output stream. In most cases these just hurt performance for no good reason.
    • Attribute Value

    Type BOOLEAN
    Nillable true

    Storage configuration
    Access Type read-write

    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • session-id-length The length of the generated session ID. Longer session ID's are more secure. 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).
