| A simple watchdog for long running processes which may stall for some reason or | |
| another. | |
| If the main thread hasn't logged progress (by updating | |
| ``self.last_progress_time``) in WATCHDOG_HARD_KILL_TIMEOUT, the watchdog | |
| thread will log an error containing the stack trace of all currently running | |
| threads then use ``kill -9`` to kill the main process. | |
| Assumes that a process monitor like supervisor or systemd will then restart |

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
