Joel Martin 8e2d749605 util.js: script load sequential execution changes. 
Related to issue: https://github.com/kanaka/noVNC/issues/205

Split out the function to load a single script to Util.load_script.

In order to get sequential load, when on IE set the script defer flag.
It is currently working on webkit and firefox but just in case also
set the script.async flag to make sure that scripts execute in the
order they are added. Scripts should still load in parallel.

Browser Requirements

  • HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS Safari, Opera 11+, Internet Explorer 9+, etc.

  • HTML5 WebSockets: For browsers that do not have builtin WebSockets support, the project includes web-socket-js, a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in WebSocket support.

  • Fast Javascript Engine: this is not strictly a requirement, but without a fast Javascript engine, noVNC might be painfully slow.

  • I maintain a more detailed browser compatibility list here.

Server Requirements

Unless you are using a VNC server with support for WebSockets connections (such as x11vnc/libvncserver or PocketVNC), you need to use a WebSockets to TCP socket proxy. There is a python proxy included ('websockify').

Quick Start

  • Use the launch script to start a mini-webserver and the WebSockets proxy (websockify). The --vnc option is used to specify the location of a running VNC server:

    ./utils/launch.sh --vnc localhost:5901

  • Point your browser to the cut-and-paste URL that is output by the launch script. Enter a password if the VNC server has one configured. Hit the Connect button and enjoy!
