improve IP detection #19

Open codemeasandwich opened 1 year ago

codemeasandwich commented 1 year ago

here are some more proxy headers

['http_via', 'http_x_forwarded_for', 'http_forwarded_for', 'http_x_forwarded', 'http_forwarded', 'http_client_ip', 'http_forwarded_for_ip', 'via', 'x_forwarded_for', 'forwarded_for', 'x_forwarded', 'forwarded', 'client_ip', 'forwarded_for_ip', 'http_proxy_connection']

The problem: A client can set any of these headed.. how can you distinguish between a bad client & a good proxy?
