Stickyness based on pattern match

[shamilton-wilkes]

Trying to replicate a Radware load balancing setup - where a string is searched for in the HTTP header, then the following field (by offset) is used as the cookie.

There doesn't seem a way to do similar on ACE, the field is too far into the header to reliably find it by offset alone.

With Layer 4 payload stickiness (

stickiness based on a string in the data of a TCP stream or UDP packet) you can stick sessions using any string

Thanks, had figured that out by the time you replied.

Has anyone got any configuration examples? Configuring the 'sticky layer4-payload' part is fine, but when it comes to applying the policy I get 'Error: Sticky type not consistent with policy map type' - despite trying various different policy types.

Hi,

Have you tried type "generic"? For example:

sticky layer4-payload WHATEVER

layer4-payload yada yada yada

serverfarm SFARM-WHATEVER

policy-map type loadbalance generic first-match LB-POLICY

class class-default

sticky-serverfarm WHATEVER

HTH

Thanks, 'generic' was the keyword I was missing.
