In Mod Security, To Prevent Slow HTTP Denial of service attack, i have used one solution from mod security. I used "SecReadStateLimit 50".
When i start apache and start opening my site in browser, it does not load site by "Problem in loading page". But when i saw apache error logs, then in logs,it printed like
ModSecurity: Access denied with code 400. Too many threads  of 50 allowed in READ state from 192.168.1.1 - Possible DoS Consumption Attack [Rejected].
Can you help me that why it does not preventing from more than 50 request from one ip address?
Is there any mistake in implementation?
