Hello,
Why does nginx logs an info log a message like ...client sent invalid host header while reading client request headers... request: "GET /keepalive.html HTTP/1.1", host: "" if the host header is empty. According to the http 1.1 specification it is legal to send an empty host header so it should not log this message since the header is not invalid. So the requests contains the host header but without a value. The call also results in a 400 instead of a 2xx or 3xx response.
Regards, B. curl -v -H "Host: " http://someserver/keepalive.html * Trying xx.xx.xx.xx... * Connected to someserver (xx.xx.xx.xx) port 80 (#0)
GET /keepalive.html HTTP/1.1 Host: User-Agent: curl/7.43.0 Accept: */*
