Socket.IO Client Configuration
|
|
|
|
|
==============================
|
|
|
|
|
|
|
|
|
|
As of 2015-10-25, the legacy `/sioconfig` JavaScript for retrieving connection
|
|
|
|
|
information is being deprecated in favor of a new API. The purpose of this
|
|
|
|
|
change is to allow partitioning channels across multiple servers in order to
|
2015-10-26 00:22:50 +00:00
|
|
|
better handle increasing traffic.

|
|
To get the socket.io configuration for the server hosting a particular channel,
|
|
|
|
|
make a `GET` request to `/socketconfig/<channel name>.json`. The response will
|
|
|
|
|
be a JSON object containing a list of acceptable servers to connect to, or an
|
|
|
|
|
error message.

GET /socketconfig/$invalid$.json

404 Not Found

|
|
Each entry in the `servers` array has `"secure":true` if the connection is
|
|
|
|
|
secured with TLS, otherwise it it is false. An entry with `"ipv6":true`
|
|
|
|
|
indicates that the server is listening on the IPv6 protocol.
|
|
|
|
|
|
|
|
|
|
You can pick any URL to connect socket.io to in order to join the specified
|
|
|
|
|
channel. I recommend picking one with `"secure":true`, only choosing an
|
|
|
|
|
insecure connection if implementing a TLS connection is infeasible.
