You are right (and your steps are exactly the right overview of what's
happening). Sorry for the confusion (it's very difficult for me to
make sure that everything is set properly, I often forget things that
seems obvious to me, but which are not in fact, sorry again).

What you want to do is to update the /Admin/Extensions/html extension,
and make all html files editable by default (eg turn putable flag to
true for the html extension). Once this is done, all html FileResource
created *after that point*, will inherit the putable flag value (eg
true), and in particular the resources created through PUT. Of course,
once you have done this, make sure you have an authentication filter
on the root resource of your server, that allows the PUT method only
to the appropriate persons...

Let me know how it goes,
Anselm.
