apache 2.0 - blank page

I had an apache 1.3.x setup for mass virtual hosting using mod_layout
that worked perfectly for all of the different sites. It would prepend a
header.html file without issue.

I am trying to do the same thing with the latest version of apache 2.0
and the pages show up blank. If I leave the module off there is no
problem and pages display normally. Here are the directives I used with
apache 1.3.x and what I am doing with apache 2.0. They are located
inside virtual host tags and header file to be prepended is a
centralized file:

 

Apache 1.3

 

LayoutMerge Off 

LayoutDefaultHandlers Off 

LayoutHandler text/html

LayoutHeader /site/apache/header.html

 

Apache 2.0

 

AddOutputFilter LAYOUT html 

LayoutHeader   /site/apache/header.html

 

Any suggestions?
