Session Persistence based on http header value using iRule

Hello

Kindly i need to apply Session Persistence based on http header :

Payment application working as follow:

1. At first request (Login) the server response with http header named "X-Token" with "fb9c2bb6-80f6-16c3-afcd-84e98976a4b7"
2. The rest of http requests will have header name "X-Auth-Token" with the same value "fb9c2bb6-80f6-16c3-afcd-84e98976a4b7" assigned by the server

I want to make sure that the client land on the same server that sent the "X-Token"

I searched for iRule that match the http header, the following iRule will work or need to modify it?

when HTTP_REQUEST {
    if { [HTTP::header exists "X-Auth-Token"]} {
        persist uie [HTTP::header "X-Auth-Token"]
    }
}

Q
