## 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:
``` caddy
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:
```php
'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:
```bash
docker compose restart caddy
```
Restart FreshRSS to ensure that it recognizes the new base URL:
```bash
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:
``` caddy
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:
```php
'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:
```bash
docker compose restart caddy
```
Restart FreshRSS to ensure that it recognizes the new base URL:
```bash
docker compose restart freshrss
```
4. **Access FreshRSS:**
FreshRSS should now be accessible at `https://subdomain.example.com/`.
