[undertow-dev] ProxyHandler timeout handling

[paroczizs .]

Hi,

I am using a ProxyHandler with a ProxyClient from a custom handler.

...
ProxyClient lbpc = getProxyClient();
ProxyHandler proxyhandler = new ProxyHandler(lbpc, requestTimeout,
ResponseCodeHandler.HANDLE_404);
...

It handles the timeout correctly however I can see some error after my
handler, the timeout logged properly.

16:43:28,566 INFO  [stdout] (default I/O-4) LWI COMPLETED  200 status 200

16:43:28,597 ERROR [io.undertow.proxy] (default I/O-4) UT005027: Timing out

Is it the normal behavior and nothing to do with it?

Is there a way to catch the timeout error and give some custom response?
