TsgcWebSocketServer_HTTPAPI › Events › OnException
Fires whenever an unhandled exception is raised while processing a client connection.
property OnException: TsgcExceptionEvent;
// TsgcExceptionEvent = procedure(Connection: TsgcWSConnection; E: Exception) of object—
OnException is raised whenever an exception escapes internal processing of the HTTP API server, for example when writing to a request that the client has already dropped, when a user event handler throws, or when an HTTP.SYS call returns an unexpected error. 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;
