Is it possible to upload a file in OpenRasta using the PUT post method?
Question with multiple answers here.
If you want to do that with an html form, you'll have to add a uri decorator to enable detection of methods that are not supported by html (HttpMethodUriDecorator I think), and then append "!METHOD" to the URI you pass in the form@action attrivute.
Then you can do your binding as usual.
If you want to do it from a standard http client, application/octet-stream should be enough, maybe with the content-disposition header (I can't quite remmeber if the IFile type is processed when using application/octet-stream).
