Anthony, I reviewed your draft. We implemented EPP over HTTP a while back, where HTTP was treated as transport in line with EPP over TCP (RFC 5734). It was shut down when it became clear that EPP over TCP was the preferred option. The difference with your draft and our implementation is that the draft defines a stateless transport and our implementation was a stateful transport. We simply framed the EPP packets using HTTP, with HTTP keep-alive, and with full support for the EPP login and logout commands. Changing from stateful to stateless would really not allow easily replacing the transport on the client-side or the server-side. We used the following HTTP properties:
1. Content length is explicitly specified 2. Chunked transfer encoding of HTTP 1.1 3. Content-type set to “text/xml” The 2-way HTTPS connection would be established, the client packet is framed as an HTTP packet and sent to the server, where the server processed the HTTP packet as it would a framed packet with EPP over TCP. All of the EPP over HTTP commands and responses would behave consistently with EPP over TCP. — JG [cid:image001.png@01D255E2.EB933A30] James Gould Distinguished Engineer jgo...@verisign.com 703-948-3271 12061 Bluemont Way Reston, VA 20190 Verisign.com<http://verisigninc.com/> From: regext <regext-boun...@ietf.org> on behalf of Anthony Eden <anthony.eden=40dnsimple....@dmarc.ietf.org> Date: Tuesday, May 22, 2018 at 12:09 PM To: "regext@ietf.org" <regext@ietf.org> Subject: [EXTERNAL] [regext] Interest in collaborating on an EPP over HTTP draft? Greetings folks! I've thrown together a repo over at GitHub to work on an EPP over HTTP draft (https://github.com/aeden/epp-over-http). I'd love to know if there are others from the community who are interested on collaborating. As a registrar, we'd love to be able to work with registries using HTTP as the transport protocol in the future. Note that the current version of this draft deals solely with EPP over HTTP 1.1, it does not consider HTTP 2 at this time. Feedback is welcome. Thanks!
