TsgcHTTP3Server › Events › OnStartup
Fires when the HTTP/3 server starts and is ready to accept connections.
property OnStartup: TNotifyEvent;
// TNotifyEvent = procedure(Sender: TObject) of object—
| Name | Type | Description |
|---|---|---|
Sender | TObject | The TsgcHTTP3Server instance that raised the event. |
Fired from Active := True (directly or through Start) after the QUIC listener socket has been bound on the configured Port (UDP) and the QUIC engine is ready to accept HTTP/3 connections. Use the event to log that the server is alive, refresh a status indicator in the UI, or start any work that depends on the listener being available.
The event reports that the listener is up, not that a client has arrived: the first client is reported by OnH3Connect. It does not fire when activation fails, since a failing Start raises an exception instead.
This event is inherited from TsgcQUICServer.
procedure OnStartupEvent(Sender: TObject);
begin
Log('HTTP/3 server listening');
end;
