websocket client example

[gitdhar]

Using the websocket client (from sample code in the README), I get this error below:
" ./openresty/lualib/resty/websocket/protocol.lua:21: attempt to index global 'ngx' (a nil value) "

I did set the package path as required.
package.path = package.path .. ";./openresty/?.lua

Is there a working sample for websocket client?

@gitdhar Please provide a minimal and self-contained example that can reproduce this. The ngx global variable should always be there in the context of OpenResty (or ngx_lua). There must be something very wrong in your OpenResty setup.
