<PRE>Hi there,
I would like to learn more about the cowboy_xxxx_handler for instance the cowboy_websocket_handler :
- is it an OTP gen_ instance ?
- how/where the websocket_handle() is called ?
- how websocket_info() relates to the Transport:send() operation and where/how this latter function is called?
I could not find the cowboy_websocket_handler behavior in the src dir. I guess i’ve missed something.
The code is clean but difficult to decipher by a erlang padawan like me.
Why do i need to understand this ?
I would like to write a generic tcp transport layer that provides an interface like the cowboy_xxx_handler to my protocol stack.
Of course i will use ranch underneath.
Neither the examples provided with ranch nor the ftp server tutorial reveals the sophisticated architecture used to handover data/context to the handler and to get reply data from the handler.
Thank you for your help.
Samir Sow
