[docs] [issue18229] attribute headers of http.server.BaseHTTPRequestHandler sometimes does not exists

[Jordan Szubert]

Jordan Szubert added the comment:

what _lowerHTTP does is try read request header 'X-Forwarded-For', but instance of request handler have attribute headers only if thing that connected to port where server listens happened to send valid enough http request

my problem is, documentation does not help write code that would not crash when client sends random bytes instead of expected http request

resolution: invalid -> 
status: closed -> open
