Cookie stickiness doesn't work

Howdy, We're trying to set up stickiness with cookies. What we've done:

 

1.Added new cookie under persistence, current settings:

 

 

  1. Set cookie stickiness in virtual server

When I do a curl request

 

curl -v -X POST --cookie 'username=test' -u "test:test" * About to connect() to testweb port 8083 (0) * Trying 192.168.9.30... * Connected to testweb (192.168.9.30) port 8083 (0) * Server auth using Basic with user 'test'

 

POST /monitor HTTP/1.1 Authorization: Basic dGVzdDp0ZXN0Cg== User-Agent: curl/7.29.0 Host: testweb:8083 Accept: / Cookie: username=test

 

< HTTP/1.1 200 OK < Server: Apache-Coyote/1.1 < Content-Type: application/json < Transfer-Encoding: chunked < Date: Wed, 23 Aug 2017 05:57:23 GMT < * Connection 0 to host testweb left intact

 

In the logs, on web servers, I see that F5 does RR without stickiness.

 

All recommendations are appreciated. Thanks

    You haven't specified the exact cookie persistence mechanism that you are seeking to implement. Have you looked into this - K83419154 ?

     

    If you are just looking for cookie persistence, "cookie insert" is a well-tested simple to implement mechanism.

    Hi,

    cookie rewrite persistence will rewrite server response cookie named "username" with it's value containing pool member information...

    you can use this irule to configure Universal persistence with cookie value:

    when HTTP_RESPONSE {
  if { [HTTP::cookie exists "Username"] } {
    persist add uie [HTTP::cookie "Username"] 3600
  }
}
when HTTP_REQUEST {
  if { [HTTP::cookie exists "Username"] } {
    persist uie [HTTP::cookie "Username"] 3600
  }
}
