The HTTPS isn't really a separate protocol, but rather a HTTP inside a SSL/TLS connection. In this context, anything about HTTP applies to HTTPS as well. The HTTP/2 is a separate protocol (again, normally used inside a SSL/TLS connection). And this protocol is not supported by the proxy module. All connections with backends using proxy_pass use HTTP/1.0 or HTTP/1.1 depending on proxy_http_version. > Example : > > upstream https_backend { > server 127.0.0.1:443; > > keepalive 16; > } > > server { > listen 443 ssl http2; > > location /https/ { > proxy_pass https://https_backend; > proxy_http_version 1.1; > proxy_set_header Connection ""; In this example, nginx will accept connections on the port 443 using SSL, with either HTTP/0.9, HTTP/1.0, HTTP/1.1, or HTTP/2 inside an SSL connection. Requests under the "/https/" prefix will be forwarded to 127.0.0.1:443 using SSL and HTTP/1.1. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
