I have a server configured with Apache and Varnish, we are using Pound to handle port 443.
Everything runs smoothly and the site speed is amazing.
I have one little bug, when clicking on an AJAX button, sometimes the request hangs for 60 seconds before posting.
I am trying to figure out where the bottleneck is and what's holding things up.
What "listener" or "debugger" can I use to trace exactly what happens on the server when I click on that AJAX button on the front end.
Beginner question, so if I'm missing the obvious please let me know
