deny limit exceeding connections

I need to deny new connections if they would exceed the limit. I can't risk to slow down current connections.

Is there a way to access the last_rate variable or do you have another suggestion for me?

There is no last_rate var in nginx.

Average rate could be gotten from (r->connection->sent / sec), but it's
different with last rate.

To calculate last rate, the time windown must be defined firstly. It
means that you want the rate
in last 1 minute or 10 seconds.

For example, If you want the last rate in 10 seconds, the limit module
could save the connection sent bytes
in every seconds looply into a 10 elements array for last 10 seconds. Then

last_rate = (r->connection->sent - sent_bytes[10] ) / 10

Ok, i thought you could expose some of your variables into the configuration. Thx for your suggestion, but i'm not really willing to delelop my own nginx plugin. Thx anyway :)
