Same cookie for multiple domains

Good morning, I am interested in how to configure Piwik to track different domains with the same cookie. There are three domains which are hosted in differents servers with the tracking code point to the piwik server. The user usually visit first one of them, and when he reads the information goes to the main domain to fill the form and register in the system. In this domain, there is another tracking code which points the piwik server. The idea, it’s to know the road choosed by the visitor to reach to the main site.

To make it possible I have to use setcookieDomain?

Thank you in advance for your interest
