Hi,
I am using the async Servlet API and NIO, by setting a ReadListener.
In the onError of the ReadListener, I am catching a SocketTimeoutException
and trying to send back an error code 408. Here is the simplified example
of what I am trying to do,
@Override
public void onError(Throwable failure) {
if(failure instanceof SocketTimeoutException) {
response.sendError(408);
request.getAsyncContext().complete();
}
}
However, Tomcat just refuses to send back the error I want and instead just
closes the connection. Am I missing something trivial or is this supposed
to be achieved in a different way?
I am using Tomcat 9.0.82 and the Http11NioEndpoint.
Has the response already been committed?
If not, a minimal (ideally a single servlet) web application that
demonstrates the issue is often the easiest way for developers to
re-create the problem.
