Limit number of sessions


Hi everybody,

we are operating an online shop system. At various points in time we have some peaks where we need to limit access to the shop to a certain amount of concurrent users. 

We are currently thinking about replacing several nginx / varnish servers with a Kemp LM. This would make the whole setup less complex.

what happens when the connection limit on all real servers has been reached? Will the user be redirected to the sorry server?

is there a better way to achive this 

thanks for any advise
