Check if a response has been sent?

Is there any way to test if a response has been sent already?

For context, I’m finding that some non-existing url queries end up just hanging, so I created

# Timeout Handling
((req,res) ->
            # Prepare
            requestInfo = {url:, ip: req.connection.remoteAddress, status: res.statusCode}

            # Attempt Timeout
                res.send(408) # Request Timeout
                console.log 'request timeout:', requestInfo
                #res.end() # End Response
                #console.log 'end response:', requestInfo
            catch err
                # Chances are the request sent fine

but even with the catch it restarts the entire process

  1. typically you just keep next()ing and connect 404s the response if you dont intervene, so I dont think this is the right way to go about it. However I believe node only sets some internal flags such as res._headerSent (or something like, can’t remember)
