I'm trying to track down some problems with the way a javascript client is interacting with an application server and would like to see the entire http payload (headers, body, and everything) that is being passed back and forth.
It so happens that there is already an haproxy server in front of the application server, so I was hoping to be able to use haproxy to provide the relevant logs. Obviously this would be bad to turn on in production, but I have a clone of the entire environment that can be isolated while I do this debugging.
Is there a way to get haproxy to log the entire http payload for POST requests going to a particular backend server?

Haproxy does not have a facility to log POST content or HTTP bodies.
Use Wireshark instead.
