The following sections provide configuration information for:
Sticky Based on a Configured String in an HTTP Cookie
•

Sticky Based on a Cookie in a
•
command
•
Sticky Based on a Cookie in the HTTP Header or
advance-balanced cookieurl command
For information on additional advanced load-balancing methods including
arrowpoint cookies, refer to the Cisco Content Services Switch Content
Load-Balancing Configuration Guide.
If the server returns a cookie that is static and uniquely identifies itself, use the
advanced-balance cookies command. This command enables the content rule to
stick a client to a server based on the configured string found in the HTTP cookie
header. A content rule with a sticky configuration set to advanced-balance
cookies requires all clients to enable cookies on their browser.
In the following configuration, the CSS looks for the cookie in the Cookie: field
of the HTTP header:
The CSS looks for the configured string prefix, which is the cookie name. In
1.
this example, the string prefix in the content rule is MyCookie=.
If the CSS finds the prefix, then it looks for the value that matches one of the
2.
string values configured in one of the services. For example, the string value
for service test 1 is server1. The CSS begins searching for the prefix and value
at the beginning of the cookie field in the header and searches the entire field
until the end of the field.
If the HTTP header spans multiple packets, the CSS searches up to 5 packets
by default; however, you can configure the CSS to search up to 20 packets
(refer to the global spanning-packets command for more details).
