Onebux Hosting's Shoutcast and Icecast plans include an HTTPS proxy audio link, which behaves like a constant MP3 stream that works in almost any website, app, or player. Unlike a standard Shoutcast/Icecast link, it has no port number, so it won't get blocked by an ISP that filters non-standard ports.
Link format
https://login-hostname/proxy/username/mountpoint
Replace login-hostname with your server's hostname, username with your CentovaCast login, and mountpoint with your stream's mountpoint (typically /stream for Shoutcast or /live for Icecast). For example, a user named "onebux" on host "cast3.yourdomain.com" would use:
https://cast3.yourdomain.com/proxy/onebux/stream
The link always serves MP3 audio, since it's supported by every major browser and player.
Metadata link
A similar link format exposes stream metadata (song titles, listener counts, etc.) for use in custom players or apps:
https://login-hostname/proxy/username/metadata-endpoint (no mountpoint this time).
Shoutcast endpoints: stats (XML), stats?json=1 (JSON), statistics (stream + server data), currentsong (current track only).
Icecast endpoint: status-json.xsl (all stream data in JSON).
