Technology Stack advice for live chat between different domains

Question

I am working on a pilot project. It's a web-based chat application (say abc.com ). I created a chat window (just the basic UI). What I wish now is from this chat window to chat with a customer support person who is on a different domain.

Say for example, there is an e-commerce website xyz.com and they have a live chat support available in their website. Is it possible to chat with the support person in xyz.com from abc.com ?

I researched a bit on this and found out this can be accomplished using WebSocket s. Can anyone throw some more light on this like whether it is feasible, the technology stack which can be used / researched further for this project etc.?

Answer 1

For a simple demo of a chat application which uses WebSocket take a look at https://demo.crossbar.io/chat/index.html#ch1 . This works across domains without a problem since all chat clients connect to a central router which distributes the messages. (Bonus: there are also clients for WAMP, the protocol this uses, for quite a few languages besides JavaScript, making adding components in other languages a breeze - see http://wamp.ws/implementations ).
