Sticky cookie

[teodor.dobrev]

Hi to all,

i have a problem with stickiness which doesn't seem to follow the logic.

I have two redundant CSS11503 with a few servers behind in a very simple configuration.

The servers are sending http cookies for hostname in the HTTP Header which looks like "HostName=ra-dc1-as-os" and i am using advanced-balance cookie clause in the content rule but the stickiness seems not matching.

Here is the config:

service OSS1

ip address 172.28.214.34

keepalive type http

string ra-dc1-as-os-01

active

service OSS2

ip address 172.28.214.54

keepalive type http

string ra-dc1-as-os-02

active

content OSS

add service OSS1

add service OSS2

string prefix "HostName="

vip address 172.28.214.80

advanced-balance cookies

active

Can you help me on how to troubleshoot more, and if a solution comes to your mind i'll be thankful :)

Thanks in advance

I would suggest to capture a sniffer trace to look at the cookie sent by the servers.

Your config looks good.

Very similar to the one in the config guide

Does your problem occur only when going through a proxy ? or when the connection is idle ?

Or does it occur for the first request of a new connection ?
