The "vnc" URI Scheme
Abstract
Virtual Network Computing (VNC) software provides remote desktop
functionality. This document describes a Uniform Resource Identifier
(URI) scheme enabling the launch of VNC clients from other
applications. The scheme specifies parameters useful in securely
connecting clients with remote hosts.

RFC 7869 The "vnc" URI Scheme May 2016
1. Introduction
Virtual Network Computing (VNC) clients are used to support remote
desktop connectivity based on the Remote Framebuffer (RFB) Protocol
[RFC6143]. It is often desirable to integrate such functionality
with other software. However, the lack of a standard method for
specifying VNC client parameters has limited such integration.
The "vnc" Uniform Resource Identifier (URI) scheme specified in this
document facilitates the launch of VNC clients from applications in
browser-based, desktop, and mobile environments. Using this scheme,
