Description
ConÞgures the cookie persistence mode for the current layer 7 service.
Syntax Description
group name The name of the server group to select whenever a client request for the current service
includes a cookie.
cookie string The ASCII name of the cookie. The current service responds only to cookies with this
name.
self Specifies that the current service uses self-identifying cookie persistence mode. In this mode,
the server cookie should contain a unique string of 7 to 15 characters to identify the real IP
web server of the specified server group.
hash Specifies that the current service uses hashed cookie persistence mode. In this mode, the
cookie contains unique information about the client. The switch computes a hash value from
this information and uses the hash value to select the appropriate server from the specified
server group.
learning Specifies that the current service uses learned cookie persistence mode. In this mode, the
switch creates a database that stores historical information about each session and uses the
stored information to match the incoming cookie with the previous connection made by the
same client and value to select the appropriate server from the specified server group.
