/* Modifications by Vlad Niculae <vlad@vene.ro> | |
Available at https://gist.github.com/vene/c0657d854ae74a4511d2 | |
Forked from https://raw.githubusercontent.com/Automattic/socket.io-client/ \ | |
0.9.16/dist/socket.io.js | |
Changes: | |
* added 'wsport' configuration option | |
Supports configuring a different port for websocket vs normal traffic. | |
This is important for hosting on OpenShift with fallbacks, as well as | |
for allowing handshakes over firewalls. | |
* connectTimeoutTimer now publishes connect_failed even if | |
"try multiple transports" is false. | |
