Replace upgrade_request function:

Code:

local upgrade_request = function(req, key)
  local format = string.format
  local uri = req.path or ''
  local query = req.query
  if type(query) == 'string' and #query > 0 then
    uri = uri .. '?' .. query
  end

  local lines = {
    format('GET %s HTTP/1.1', uri),
    format('Host: %s', req.host),
    'Upgrade: websocket',
    'Connection: Upgrade',
    format('Sec-WebSocket-Key: %s',key),
    'Sec-WebSocket-Version: 13',
  }
  if req.port and req.port ~= 80 then
    lines[2] = format('Host: %s:%d', req.host, req.port)
  end
  if req.userinfo then
    local auth = format('Authorization: Basic %s', base64enc(req.userinfo))
    tinsert(lines, auth)
  end
  tinsert(lines,'\r\n')
  return tconcat(lines,'\r\n')
end
