Reverse Proxy Subsonic with Apache

Subsonic is a web-based media player for playing audio and video files through a web browser. You can reverse proxy Subsonic using Apache

See my blog post on using Apache as a reverse proxy for more detailed information on Apache configuration files.

The below configuration expects the backend Subsonic port to be non-ssl as the encryption will be offloaded to the Apache reverse proxy server. The reverse proxy URL will be encrypted and available on the default SSL port 443. This has the advantage of not using any CPU on the Subsonic server for encrypting traffic allowing it to concentrate on transcoding.

Add the below text to a new sites-available Apache configuration file.
vi /etc/apache2/sites-available/subsonic

<VirtualHost *:443>
    SSLEngine On
    SSLCertificateFile /ssl-certs/cert.cer
    SSLCertificateKeyFile /ssl-certs/key.key
