Temporary custom HTML page

[ContemporaryFusion]

Hi guys,

I hope i am asking this in the right place - please feel free to move it if not.

I've ordered a secure certificate for my new Zimbra server, and the guys at the signing authority (Globalsign) have asked me to add a temporary HTML page to prove my control of the domain. Thats fine except having searched the Wiki and the forums it suggests that modifying Jetty to show custom HTML pages is a bad idea. I'm after a temporary fix for this - does anyone know of a zimlet or an easy way to provide something for them? Am I best "turning off" webmail for a day using a default HTTP server style setup? If so as Jetty is using port 80 am I best using this or installing a fresh copy of nginx/apache/jetty on the machine for a few days for this page?

Kind regards,
Dave
