Hi! You should run target/main.go at your server. Checker should connect to your target using proxy. The target will respond with some information about request and checker will make decision about proxy.

I wrote a new validation tool using PHP to mimic target
I want to point out that checkers often have exceptions leading to exit (#1)
In php, I can catch exceptions and skip over the parts where exceptions occur
Can't golang do that?
