TsgcWebSocketServer_HTTPAPI › Properties › Host
Hostname or IP address used to build the URL registered with the http.sys driver.
property Host: string read GetHost write SetHost;'127.0.0.1'
When Host has a value the server combines it with Port to register a single URL (for example http://127.0.0.1:80/) at start-up. If you need to listen on several IP addresses or hostnames simultaneously, clear Host, call Bindings.Clear and register each endpoint with Bindings.NewBinding. Use + as a wildcard host to accept traffic on every local interface, or a specific IP / DNS name to restrict the listener. Host changes take effect the next time Active is toggled.
