Listener on (WebDAV) directory?

Question

I'm searching for a way to know when a file of a directory is modify, create or delete.

Thanks for any interest to my problem!

There is no universal way to do this. Some servers may provide facilities to do this, but it highly depends on which server you're running.

So lacking that, the only universal thing you can do is issue PROPFIND requests every x seconds and see if something changed.
