Is it possible to "create with overwrite"? This is needed for the HTTP PUT implementation, but doesn't seem possible.

We started with this:

xrdreq.open.options = htons(kXR_mkpath | kXR_open_updt | kXR_new );

this successfully creates the file, but doesn't allow it to be overwritten. So, it was then changed to:

xrdreq.open.options = htons(kXR_mkpath | kXR_open_wrto );

This overwrites the file, but doesn't allow one to be created.

A bit of greping through the code, it seems like this does work

xrdreq.open.options = htons(kXR_mkpath | kXR_open_wrto | kXR_delete);

Any thoughts or opinions on this? It would imply that HTTP PUT requires delete permission (which I recall is distinct from being able to create files?)
