Thank you sir for your quick reply. I am now able to give custom error code for my HAproxy configuration. However I am facing one more issue .
With the above approach HAproxy is rejecting each and every calls once the limit has crossed. It is behaving as a circuit breaker . But my requirement is to have a throttling for example every 10 second I should allow 200 request and anything more than 200 will be rejected. Is there any way I can achieve this .Please help me to configure the same. Thanks in advance Samrat On Fri, Aug 26, 2016 at 10:16 PM, Chad Lavoie <clav...@haproxy.com> wrote: > Greetings, > > On 08/26/2016 09:14 AM, Samrat Roy wrote: > > Hello Sir, > > > > down votefavorite > <http://stackoverflow.com/questions/39166887/haproxy-limiting-the-connection-rate-per-user#> > > I am trying to achieve rate limiting using HAProxy.
