PUT / DELETE request now allowed

Is there are option to allow PUT or DELETE requests? Using the api with POST request works just fine, I use it to upload images which are stored in the input folder, but I would like to override or create a new file with the same file name. If the file already exists, the file is stored with a new file name (image (1)).
I have tried to use PUT or DELETE request and this gives the followong error:
_"HTTP/1.1 405 Method Not Allowed"_
