Hi Dean,
Thanks for your answer - it is not completly satisfying to me.

Using SSI for standard headers and footers in *.html documents is 
a practical design method used by an increasing number of webmasters.
(Most of them not even know that they prevent apache to send a 
"Last Modification" value when using SSI and thus prevent any
sensible caching of their documents.)

We will use "ExpiresByType" for setting a default Expires value for all
*.html documents and "meta files" with Expires for any exception as a
workaround. (Using "XBitHack" is a hack in my opinion)

But anyway - workarounds may be a solution for me - but apache should work
with the normal configuration as good as possible. 

I think it's in your interest to provide documents to as muche people 
as fast as possible. In the next years only caching will give some 
help against overloaded networks *and* overloaded web servers.

I hope you will reconsider to find a way to improve your great software
to be more cache friendly.
(There are also endusers using a webserver not only providers.)

Best regards,
