* In this case, if we succeed in using an existing server session, no "Set-Cookie" header will be returned, and therefore no
* "Cookie"-keyed property would be set on the service context. So, let's copy our request context HEADER_COOKIE key to the service
* context now to prevent the "no cookie" exception in BindingProvider.setupSessionContext. It is possible the server does not support
