Using Caddy as a Reverse Proxy

How to configure Caddy as a reverse proxy to serve FreshRSS through a subfolder or subdomain

Using Caddy as a Reverse Proxy with a Subfolder

To set up FreshRSS behind a reverse proxy with Caddy and using a subfolder, follow these steps:

1. Configure Caddyfile:

   Update your Caddyfile with the following configuration:

   example.com {
       redir /subfolder /subfolder/ # Just to redirect users that are missing the closing slash to the correct page
       handle_path /subfolder/* { # Actually configures the used subfolder (also internally strips the path prefix)
           reverse_proxy freshrss:80 { # Enables the reverse proxy for the configured program:port
               header_up X-Forwarded-Prefix "/subfolder" # Sets the correct header for the login cookies
           }
       }
   }
   

   Replace example.com with your actual domain and the four instances of subfolder with the subfolder where you want FreshRSS to be hosted.

   NOTE: Ensure that the Docker container name for FreshRSS (freshrss in this example) matches the name used in the Caddyfile configuration.

2. Update FreshRSS Configuration:

   Open the config.php file in your FreshRSS installation and update the base_url parameter to match the subfolder configuration:

   'base_url' => 'https://example.com/subfolder',
   

   Replace example.com with your actual domain and subfolder with the same subfolder name specified in the Caddyfile.

3. Restart Caddy and FreshRSS:

   Restart Caddy to apply the configuration changes:

   docker compose restart caddy
   

   Restart FreshRSS to ensure that it recognizes the new base URL:

   docker compose restart freshrss
   

4. Access FreshRSS:

   FreshRSS should now be accessible at https://example.com/subfolder.

Using Caddy as a Reverse Proxy with a Subdomain

To set up FreshRSS behind a reverse proxy with Caddy and using a subdomain, follow these steps:

1. Configure Caddyfile:

   Update your Caddyfile with the following configuration:

   subdomain.example.com { # The url Caddy should serve the proxy on
       reverse_proxy freshrss:80 # Enables the reverse proxy for the configured program:port
   }
   

   Replace example.com with your actual domain and subdomain with the subfolder where you want FreshRSS to be hosted.

   NOTE: Ensure that the Docker container name for FreshRSS (freshrss in this example) matches the name used in the Caddyfile configuration. NOTE: Make sure to set the DNS Records for your configured subdomain.

2. Update FreshRSS Configuration:

   Open the config.php file in your FreshRSS installation and update the base_url parameter to match the subdomain configuration:

   'base_url' => 'https://subdomain.example.com/',
   

   Replace example.com with your actual domain and subdomain with the same subdomain specified in the Caddyfile.

3. Restart Caddy and FreshRSS:

   Restart Caddy to apply the configuration changes:

   docker compose restart caddy
   

   Restart FreshRSS to ensure that it recognizes the new base URL:

   docker compose restart freshrss
   

4. Access FreshRSS:

   FreshRSS should now be accessible at https://subdomain.example.com/.
