Max clients and ListenBacklog config

[macnoobie]

I need to limit number of clients that can connect to the server, say 1 at a time , and redirect others (2,3,4,...) to an error-try-again-later-page.

It seems like what I need is to set up the MaxClients to 1 and ListenBacklog to 0 (so there is not queue), but this doesn't really do it for me. Oddly enough, sometimes in the error log it says max client is reached, but most of the times, the rest of the clients were just put in queue

anyone can help me with this issue?

Thanks

anyone have some hints to how I can approach this?
