cookie to direct all subsequent traffic within a given session to
the corresponding backend server.
— If the backend server embeds a string of characters as the
cookie value, the VPN Gateway will perform a hash on the
cookie value. The VPN Gateway will then select a backend
server and direct all subsequent traffic within a given session to
the same backend server, based on the hashed cookie value.
•
rewrite (r): Rewrite mode. When selecting this mode, the backend
server must be configured to return a special persistence cookie,
which the VPN Gateway is configured to recognize. When
recognized, the VPN Gateway intercepts the cookie and rewrites the
value to include server-specific information before sending it on to
the client. Subsequent connection requests (within a given session)
from the same client are sent to the same backend server.
For configuration examples including the three different cookie-based
persistence modes, see the section "Configuring Cookie-Based
Persistence" in the "Load Balancing of Backend Servers" chapter of the
Application Guide for SSL Acceleration.
Sets a cookie name that can be used to identify the cookie used by the
virtual SSL server.
The default cookie name is ISDSSL.
Sets a domain name that is valid for the cookie, e.g. .example.com.
In global server load balancing (GSLB) configurations, the case might
be that the client browser returns the cookie to another server than the
server from which it was originally sent, if they both respond to the
same host name (e.g. www.example.com). Since this other server will
not recognize the cookie id, it will forward the cookie to other servers
using the domain name specified as cookie domain name.
Only used for Insert mode.
