## Foreword

This guide assumes that:

- Shaarli runs in a Docker container
- The host's `10080` port is mapped to the container's `80` port
- Shaarli's Fully Qualified Domain Name (FQDN) is `shaarli.domain.tld`
- HTTP traffic is redirected to HTTPS

## Apache

- [Apache 2.4 documentation](https://httpd.apache.org/docs/2.4/)
    - [mod_proxy](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html)
    - [Reverse Proxy Request Headers](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#x-headers)

The following HTTP headers are set by using the `ProxyPass` directive:

- `X-Forwarded-For`
- `X-Forwarded-Host`
- `X-Forwarded-Server`

```apache
<VirtualHost *:80>
    ServerName shaarli.domain.tld
    Redirect permanent / https://shaarli.domain.tld
</VirtualHost>

<VirtualHost *:443>
    ServerName shaarli.domain.tld

    SSLEngine on
    SSLCertificateFile    /path/to/cert
    SSLCertificateKeyFile /path/to/certkey

    LogLevel warn
    ErrorLog  /var/log/apache2/shaarli-error.log
    CustomLog /var/log/apache2/shaarli-access.log combined

    RequestHeader set X-Forwarded-Proto "https"

    ProxyPass        / http://127.0.0.1:10080/
    ProxyPassReverse / http://127.0.0.1:10080/
</VirtualHost>
```
