Limiting HTTP/HTTPS GET and POST Flood Attacks using an iRule

Hey folks,

I am interested in seeing if there is an existing iRule that can rate limit HTTP/HTTPS GET/POST Flood Attacks. I have search DevCentral and found a few similar but many look as though they are based on individual URI's and Source IP's.

In my specific instance, I want to limit based on source IP. If the source goes over the specific POST/GET limit within a specified time frame, they then are dropped automatically for a specified period of time.

I have looked into ASM, but do not have a budget at this time to purchase that functionality.

Any help would be appreciated.
