Yes this is very cool. BTW, EFS already supports FTP port numbers.

This is an known and fixed bug. Unfortunately that doesn't help you right
now unless you want to upgrade to the latest unstable release.

This is not some much a ZServer issue as a Zope PUT handling issue. For the
most part the same code that handles FTP put handles HTTP PUT and WebDAV put.

Basically Zope looks for a content-type header on the request, barring
that, it uses the mimetypes module to guess the mime-type from the file
extension. Then it creates a Zope object that it chooses as most closely
matching the content-type.

Of course there are problems with this approach. What if you create a Z
Class and want to associate a file extension or a mime-type with it? What
if you want DTML Documents, rather than DTML Methods to be created by PUT?
What if you want WebDAV puts to treat .txt files differently than FTP puts?
Etcetera, etcetera.

I don't think this issue has been a priority for anyone so far. If it is
for you, we're open to suggestions. (And patches ;-)
