For context: RFC 7230 : "If the target URI includes an authority component, then a client MUST send a field-value for Host that is identical to that authority component" "If the target URI includes an authority component, then a client MUST send a field-value for Host that is identical to that authority component" "A server MUST respond with a 400 (Bad Request) status code to any HTTP/1.1 request message that ... contains ... a Host header field with an invalid field-value." When the host_verify_strict directive is set to "on" then Squid will produce a 4XX status code to any traffic received with invalid Host headers. A Host header that conflicts with info in the URL is always invalid.
