Hello List, I have a setup where I put an ancient host running a perl-cgi app behind an nginx reverse proxy.
The http reverse proxy works fine however if I try: curl -v --anyauth -k https://app.test.lan/cgi-bin/page.pl I get: http2 error: Invalid HTTP header field was received: frame type: 1, stream: 3, name: [defined(%hash) is deprecated at page.pl line 14.], value: [] However if I define http1.1 it works fine: curl -v --http1.1 --anyauth -k https://app.test.lan/cgi-bin/page.pl I guess all modern browsers default to http2 these days so that I can specify it for curl is not a big help. I need this to work out of the box. I have read that Nginx with the listen 443 ssl http2; directive will downgrade the connection to http1.1 automatically if it's negotiated... otherwise my previous test wouldn't work at all. What I have tried is adding this version directive into the location: location / { proxy_pass http://10.9.0.90/; proxy_http_version 1.1; } Makes no difference. Any idea how to fix this without touching the original app or the original webserver.
