Websockets support
LinkedIn recently donated an implementation that allows for proxying of WebSockets. It supports the basic upgrade path for a web socket, and is configured using normal remap.config rules:
| Code Block |
|---|
map ws://www.example.com ws://ws.example.com:9090
|
This is still slightly in "experimental" mode, so we're definitely looking forward to hear feedback from people using this.

Proxy -- on
root@cosmo 422/0 # traffic_line --clear_alarms all
No Alarms to resolve
