Limit IPs connections to 4 per minute?

[Sands]

I get
attacked" every day now with a connection that is from a different URL each day.

They connect from a URL at 6 per second for about an hour and half.

Security cannot stop this.

Does any one know of any software or script that I can use to govern Connections and limit them.

There must a script I can use to limit IPs to a predetermined number of connections at once and per an amount of time.

Would be a htaccess script I can load?

Any help would be appreciated.

have you been able to determine what bot is doing it? if so, you may be able to block the bot via .htaccess or work with HG to block it via modsecurity.

and what do you mean, specifically, when you say "Security cannot stop this"? If you give us a little more info about what you know about this and what you've tried, we may be able to provide some ideas...
