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

2013-10-06 Thread 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
