[Zope] Setting a document's domain

Hi there, I have posted a similar problem previously, but might have explained it badly: Is it possible to change a Zope generated document's domain? I need to communicate with my Zope from JavaScript served from a different server. I cannot access the window generated by my Zope server as this causes an access denied error (the page served by Zope is from a different domain as the page with the JavaScript). The only way around this can be to set the document's domain to the same domain of the JavaScript document. Any help would be appreciated. Regards Etienne
