Edit Question
Title
Body
In an ExpressJS set up on top of NodeJS, I have a bit of code like this: app.get('/keys/readresults/:keyname', basic_auth, function(req,res){ res.writeHead(200, {'content-type': 'text/json'}); setInterval( go_to_database_and_get('stuff', function (database_replies) { res.write(database_replies) }) ,5000); }); The code is wrote like that for simplicity (if anyone wants the real code I'm happy to post it in some pastebin). What happens when I curl -u username:password http://localhost:4000/keys/readresults/key is exactly what I wanted to happen: I get a 200 status header, it checks the database for any results I want and writes the response back to me, then waits 5 seconds and searches for new results in the database and writes the response again, and so on every interval of 5 seconds. The problem is that when I exit curl, the loop keeps on going forever. How do I tell express or nodejs that it's supposed to end that loop (with clearInterval I guess) as soon as the request has ended ?
