Reverse proxy

If Shaarli is hosted on a server behind a reverse proxy (i.e. there is a proxy server between clients and the web server hosting Shaarli), configure it accordingly. See Reverse proxy configuration. In this example:

• The Shaarli application server exposes port 10080 to the proxy (for example docker container started with --publish 127.0.0.1:10080:80).
• The Shaarli application server runs at 127.0.0.1 (container). Replace with the server's IP address if running on a different machine.
• Shaarli's Fully Qualified Domain Name (FQDN) is shaarli.mydomain.org.
• No HTTPS is setup on the application server, SSL termination is done at the reverse proxy.

In your Shaarli configuration data/config.json.php, add the public IP of your proxy under security.trusted_proxies.
