more verification:

1. write a nodejs websocket service:

# ws.js
var ws = require("nodejs-websocket")

var server = ws.createServer(function (conn) {
    console.log("New connection")
    
    conn.on("text", function (str) {
        console.log("Received " + str)
        conn.sendText(str.toUpperCase() + "!!!")
    })
    
    conn.on("close", function (code, reason) {
        console.log("Connection closed")
    })
    
}).listen(8088)


2. write a ruby test client:

# ws-client.rb
require 'faye/websocket'
require 'eventmachine'

EM.run {
    ws = Faye::WebSocket::Client.new('http://127.0.0.1/ws/')
    
    ws.on :open do |event|
        p [:open]
        ws.send('Hello, Martian!')
    end
    
    ws.on :message do |event|
        p [:message, event.data]
    end
    
    ws.on :close do |event|
        p [:close, event.code, event.reason]
        ws = nil
    end
}

3. setup httpd proxy properly:

LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so
...
ProxyPass /ws/  ws://127.0.0.1:8088/
ProxyPassReverse /ws/  ws://127.0.0.1:8088/
...
LogLevel debug

4. start nodejs service:

[weli@dhcp-66-78-87 work]$ node ws.js

5. start httpd

[weli@dhcp-66-78-87 sbin]$ sudo ./apachectl restart

6. run ws-client.rb

[weli@dhcp-66-78-87 work]$ ruby ws-client.rb
[:open]
[:message, "HELLO, MARTIAN!!!!"]

nodejs server side:

[weli@dhcp-66-78-87 work]$ node ws.js
New connection
Received Hello, Martian!
