Description
I had set up proxying with
proxy_pass https://redacted.example:443;
proxy_ssl_trusted_certificate /etc/nginx/redacted.crt;
proxy_ssl_verify on;
proxy_set_header Host $host;
proxy_buffering off;
proxy_http_version 1.1;
The origin server runs Apache/2.4.41 as bundled with Ubuntu 20.04.
With this setup, Safari refuses to load pages proxied by nginx from the Apache origin server https://bugs.webkit.org/show_bug.cgi?id=218560 even though requests served directly by nginx or proxied from Jetty work OK.
The problem is solved by adding
proxy_hide_header Upgrade;
Since Upgrade is a per-hop HTTP header, nginx should, by default, not forward it. (It seems that sending the header is an Apache bug.)
