Защита от DDoS сайтов в Chrome

Если часто обновлять страничку, которая выдает код 5xx, то на 2й-3й раз Chrome выдаст предупреждение, что так делать не нужно:

In order to prevent Distributed Denial of Service (DDoS) attacks from being perpetrated by web pages and extensions that run within Chrome, the HTTP throttling mechanism keeps track of errors requesting a given URL (minus the query parameters), and after a few 5xx errors in a row, starts exponentially increasing an interval during which requests to the given URL are disallowed.

You may enable or disable the feature below. Please let us know if the feature is causing problems for your web site. More details and contact information at http://dev.chromium.org/throttling.

Throttle HTTP requests if the server has been overloaded or encountered an error.
