ACE generating 302's upon exceeding license?

[r.waterman]

Hi all

I was told that its a "feature" of the ACE whereby if bandwidth/connections exceed max allocation, that the ACE will send a HTTP status code of 302 back to the client. Now in our case, we are using layer 4 VIPs (albeit matching on ports 80/443). I'm having a hard time believing this, as in my mind either a TCP reset would be sent or the traffic would be simply dropped.

Is there anyone who can tell me the exact behaviour seen when any counter has exceeded max allocation?

Thanks

Hi,

If BW/connection box wide/context wide usage is more than allocated, then traffic would be dropped. Once the connections/BW fall below the max allocated, then it will start to accept traffic again.

There is no redirect here unless you are talking about backup real server in a serverfarm or backup serverfarm/partial failover etc.
