[Zope] including external html fragments

[Sean Robertson]

Can anyone help me figure out how to include an external HTML fragment?
Here is the basic code fragment, with (obviously) incorrect include
statements.  I looked at the docs, but am having a hard time making sense
out of it.

 <!--#if mainclass == Employment-->
     <!--#include http://data.pilotonline.com/connect2/blue_header.html-->
 <!--#else:-->
     <!--#include
http://data.pilotonline.com/connect2/default_header.html-->
 <!--#/if-->
