automatic type identification (by extension) in virtual DAV repositories

[Chris Knight]

So, Catacomb and other mod_dav backends that handle GET requests would 
like to have the Content-Type of resources be automatically identified 
based on the path information of that resource in the same manner as 
file resources.

How would I best approach this problem? It appears that the mod_dav.c 
hooks are defined as MIDDLE as is the mod_mime.c hooks...Should I force 
a specific ordering of execution? Only other problem is find_ct in 
mod_mime.c wants to see the finfo structure which doesn't apply to 
virtual resources.

I can't call find_ct directly, nor can I get at the mime_dir_config 
information to map the extension back to a Content-Type. Ideas?

It seems to me that the mime_dir_config information should be made 
public or at least some methods for converting extension to Content-Type 
(and visa-versa?)
