Nginx variable to know the number of active connections

Server NGINX

Hello,

Is there a way to get the number of active connections in order to
activate
or a not a cache mechanism when nginx is in a high trafic period?

The following variable are available in the
ngx_http_stub_status_module:

$connections_active,
$connections_reading
$connections_writing
$connections_waiting

Oh great, so i can parameter using a cache mechanism using
fastcgi_cache_path or the Lua Module SRCACHE for my PHP upstream block
simply by checking for example $connections_waiting on each request.
I don’t know exactly what would be a right setting for using a cache by
testing $connections_waiting. I have to do some tests.

thank you
