André, thanks a lot for that great and detailed answer! It's like everyone says the support from this mailing list is perfect.

I will only need GET, LOCK, PROPFIND and PUT. Other requests like COPY or DELETE shouldn't be enabled for the TWiki files. When someone tries to open an attachment as WebDAV file from an office tool I need to run the TWiki function that checks if the user has the rights to edit the attachment - for every page in the TWiki one can restrict view and edit access to certain users/groups. After uploading files (via DAV) I also need to run some functions from the TWiki, to run the version management, check if the file name needs to be protected and so on. So I think for that, your idea about wrapping mod_dav with some mod_perl handlers sound really interesting and could be the best way to combine existing functionality with the TWiki without changing someone else’s code and with the support for mod_dav. I will need some more time to go to all the links and ideas you gave me, but by now I'm not feeling that confused about mod_perl any more and you helped my see the problem and a possible solution in a much clearer way. Thanks again for the help, Carla
