Protocol Handler Registration via Browser Extensions – make everything intensely

Custom URL schemes have traditionally served as an integration bridge between the browser and external capabilities. Schemes such as mailto: and tel: allow navigation to trigger actions beyond ordinary HTTP resource retrieval. The HTML Standard formalizes this mechanism through the Custom Scheme Handlers API, which enables websites to register themselves as handlers for specific URL schemes.

What i find interesting about this article is not the realization that MPI is like email, but the reverse, that human collaboration using messages is like MPI. The suggestion to use SMTP as a transport for things much more complex than emails is something worth looking at. It relates to my belief that the instant messaging difference does not come from the new protocols like XMPP for jabber, but from the new client interface that facilitates short messages in a conversational style. SMTP is equally (if not more) capable of transporting these messages. Sure, SMTP is not designed for "instant" messaging. but todays use of SMTP where my local SMTP server talks directly to your SMTP server, makes email is just as instant.

HTTP Semantics

The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document describes the overall architecture of HTTP, establishes common terminology, and defines aspects of the protocol that are shared by all versions. In this definition are core protocol elements, extensibility mechanisms, and the "http" and "https" Uniform Resource Identifier (URI) schemes. This document updates RFC 3864 and obsoletes RFCs 2818, 7231, 7232, 7233, 7235, 7538, 7615, 7694, and portions of 7230.
