Persistence in SOAP communication

[tonesco01]

Hi guys,

I need to balance a xml soap request, but I need to do a persistence via cookie in this request. The usual implementation doesn't work. I have the cisco applience 4700. It's possible to insert the cookie in this communication?

Hi,

As far as I know SOAP exchange information over HTTP. ACE should be able to insert cookie. This cookie will be exchanged only between client and ACE. ACE strips off the cookie before forwarding to the server.

Below is the config example for the same.

Thanks Ajay,

The problem is that this communication is server-to-server and no by a browser. It's called by a web service.I tested the normal cookie insert, but in the capture i could not see the insertion.

Hi,

I am assuming this setup something like this :

Client >> VIP1 >> ACE >> server1

Server1 >> server 2

Ideally if you want to insert cookie then you should define another VIP for the server initiated connection and use cookie insert.
