Daniel,

I'll now explain that. Let A is the host-under-debugging (HUD). There is 
another host, B, which is debugger. Let there is some new HTTP server 
software on A. B's sending requests with different methods, headers and 
entity to test A for appropriate processing of headers. Let B is sending 
the request with header X-Foo, which is to be used or already used 
widely among the Internet. But A does not recognize it. But it is not 
easy for developers to get known this. If discussed header is used, B 
testers can simply analyze A's answer (as it is to be done at all) to 
find out the problem and fix it. That is debugging purpose, IMO.

Hope I explained everything clearly.

Any suggestions are welcome.

All the best,
Mykyta Yevstifeyev
