Description
A unique socket address used by the WebSocket backend. IPv4 sockets, IPv6 sockets, and Unix Domain Sockets (UDS) are supported. IPv4 and IPv6 sockets can be used for communication over the network. UDS can only be used when the WebSocket backend resides on the same machine as the server.
Syntax
IPv4/IPv6 address:port, UDS://path, or unix:path
Example
127.0.0.1:5434
UDS://tmp/lshttpd/php.sock
unix:/tmp/lshttpd/php.sock
Tips
If the WebSocket backend runs on the same machine, UDS is preferred. If you have to use an IPv4 or IPv6 socket, set the IP address to localhost or 127.0.0.1, so the WebSocket backend is inaccessible from other machines.
Unix Domain Sockets generally provide higher performance than IPv4 or IPv6 sockets.
