HTML forms vs PUT and DELETE

Hi,

can anybody point me to actual uses cases for this?

For DELETE: being able to send a DELETE request from a form (without 
requiring script) sounds fine in theory; but if the server actually does 
what it's told do and returns 200 or 204, then what? How does the web 
application continue from there?

For PUT: this doesn't sound very useful unless it was possible to 
control both the Content-Type and the full payload.

What am I missing something here?

Best regards, Julian
