Netscaler & Let's Encrypt HTTP Challenge

Greetings!

I'm using a Netscaler to front end SSL for some websites. I have a setup where certbot automatically renews the certificate and then updates the netscaler with python. What I would like to do is create a content switch policy that directs the HTTP challenges to the certbot box and redirects all other http requests to https. Does anyone know what that request looks like? Let's Encrypt's quick start documentation is a little vague and says to "open port 80".

I may take a packet capture if I have some free time and I'll post back if I get some results that answer this question.
