how to limit a client IP from continuously opening connections to the server

Hi guys, I'm a noob to iRules and was wondering if there was a way we could write up an iRule to limit the amount of connections a user can open over a course of a period of time. We got hammered by...

The above iRule seems to be dealing with android(mobile client). if you know the specific client IP which is causing trouble, you might just want to block that one.

 

otherwise, you might want to try the irule at this link.

 

https://devcentral.f5.com/questions/help-need-to-create-a-irule-for-limit-client-connection (it might need to be tuned in order to match your specific requirements). This irule is more generic and filters at layer 4 (more efficient) rather than layer 7 like the one you posted.
