TsgcWebSocketProxyServer › Events › OnException
Fires whenever an unhandled exception is raised while processing a downstream connection or its upstream forwarding.
property OnException: TsgcExceptionEvent;
// TsgcExceptionEvent = procedure(Connection: TsgcWSConnection; E: Exception) of object
—
OnException is raised whenever an exception escapes internal processing, either on the downstream WebSocket side (writing to a socket that the client has already dropped, a user event handler throwing, a failed TCP read...) or on the upstream TCP link the proxy uses to forward data. The E parameter exposes the exception instance so the application can log the message or react to specific classes. By default a disconnection raises an exception here; set Options.RaiseDisconnectExceptions to False to suppress those disconnect-related exceptions.
procedure OnException(Connection: TsgcWSConnection; E: Exception);
begin
WriteLn('#exception: ' + E.Message);
end;
