Health check curl example

[Marc Roos]

I am not understanding how this health check[1] script should work. From 
the commandline it works fine when I type a PING I get a PONG. But how 
do I do a curl to this 5001 port? 

Tried something like this:

bash-5.0# curl http://localhost:5001/
curl: (56) Recv failure: Connection reset by peer

bash-5.0# curl http://localhost:5001/PING
curl: (56) Recv failure: Connection reset by peer
