RubyForApache and text/html

Hi all,

I'm trying to get Ruby to run allongside my local WinXP testing server
(from xampp -> http://www.apachefriends.org/en/xampp.html).

Apace can now send on output from my Ruby files, but one little
problem: everything comes out as:

Content-Type: text/plain; charset=ISO-8859-1

Is there any way that I can change this to text/html or application/xhtml+xml?

Is using RubyForApache a good way to go about setting up Ruby?

All my previous attempts have tended to the Internal Server Error type
results, or the "ownload this ruby file" results...

Thanks,
Douglas
