> I guess the Size option from draft-li-core-coap-size-option-00 could be extended such that a CoAP GET request including Size=0 is treated as a request to get the size of the resource representation (but not the resource payload) and so could be translated to and from an HTTP HEAD (and could return Content-Length to a CoAP requester).



Good suggestion. I will add this in -01, if there are no other opinions.



Thanks,

Kind Regards
