in the request body, encoded as specified by the enctype attribute. this can be differentiated on the server as is already done for POST by dispatching based on content type, automated agents can upload xml, json, etc and user agents can upload form-data or x-www-form-urlencoded. cam On 30/03/2011, at 4:06 PM, Julian Reschke wrote: > On 30.03.2011 16:58, Cameron Heavon-Jones wrote: >> >> >> On 30/03/2011, at 3:25 PM, Julian Reschke wrote: >> >>> On 30.03.2011 16:02, Cameron Heavon-Jones wrote: >>>> Existing servers don't do this for PUT or DELETE but then existing servers don't currently support these methods from forms anyway. >>> >>> What exactly does it *mean* to support these methods "for forms"? >> >> It is so that a user can interact with a resful service using plain html (no ajax) in the same way that automated agents can. >> >> This means a user must be able to initiate any method of HTTP request, and the only way of doing that in html is through a form.

This is the way that this currently works for automated agents, there is nothing special about a user agent which precludes it from sending these types of requests. A form is just a UI element for allowing a user to interact with the same service which everything else already does. >> >> For a form to send a DELETE doesn't seem to make much sense, but this is only due to the flexibility of the form element in being able to capture any amount of request data. This data seems at odds with a method like DELETE which appears to be a non-configurable operation. However, it does make sense that for an idempotent operation there almost should be some some additional arguments - maybe even just a hidden version number. >> ... > > So for PUT, where do you want the form fields to go?
