Sample code for httpresponse.headers() usage with 'set-cookie'

setcookie.agent.nut

http.onrequest(function(request, response){
	// This issues cookies with path=/, which means that the browser
	// sends them to any page on agent.electricimp.com;
	// this means that other agents can read it.
    
	local url = http.agenturl()
    
	// url is https://agent.electricimp.com/agentID, so use 'split' to
	// generate an array of sub-strings separated by /
    
	local urlParts = split(url, "/")
    
	// The agentID is the third element in the array
    
	local pathField = "path=/" + urlParts[2]
    
	// Add the pathField to your cookie header

	response.header("Set-Cookie", "cookie=123456789 ; max-age=3600 ; " + pathField)

	// Issue the response to the browser

	response.send(200, "OK")
	})
