XML response gets cut

aldec · June 20, 2021, 2:14pm

1. Caddy version (`caddy version`):

v2.4.3 h1:Y1FaV2N4WO3rBqxSYA8UZsZTQdN+PwcoOcAiZTM8C0I=

2. How I run Caddy:

a. System environment:

Ubuntu 20.04, systemd

b. Command:

systemctl start caddy

c. Service/unit/compose file:

d. My complete Caddyfile or JSON config:

gis.dvisca.de {
	file_server

	handle /qgisserver {
		reverse_proxy unix//var/run/fcgiwrap.socket {
			transport fastcgi {
				env SCRIPT_FILENAME /usr/lib/cgi-bin/qgis_mapserv.fcgi
				split ""
			}
		}
	}
}

3. The problem I’m having:

I’m trying to get QGIS server (a FCGI application) to work with Caddy. So far the basics are working but now my responses get cut. The connection gets terminated and I get an incomplete response.

4. Error messages and/or full log output:

Looks like this error is being returned in the response headers. Seems like an issue in your QGIS app.

aldec · June 20, 2021, 3:44pm

Yeah… very strange. It should absolutely not cause a problem like this, but fixing it actually helped. Thanks!
