// UPDATE: Firing two requests curl in two Terminal windows resolves the issue below
// This code is good. The test (using Firefox) was bad.

//Two web requests in close succession, still have to wait 20 secs for 2nd request to complete...
//OUTPUT AS FOLLOWS:
//
//running... 12:12:00
//got request 12:12:06
