[Zope] Flash intro

Do I need to do anything within Zope to enable a Flash intro to display? The intro does come up OK when I use the full URL eg http://mysite:8080/myflashsite but when redirected through Apache to http://myflashsite/ it will not load. The title of the page shows which indicates the page has been found but it stops without loading the flash page. Could this a problem in the Apache redirection? And before anyone suggests that I shouldn't use flash, it isn't my decision and I can't do anything about it. -- John
