Limiter (botnet & overload protection)

If your web is attacked by botnet, you can include this script into it and prevent server crash.

Just set up a number of allowed approaches and controled time. (for ex. 1000 users/1 min)
If there were connected 1001 users in 1 minute, web will be shuted down by generated htaccess file.
There is a second file(you should execute it with cron) to automaticly remove htaccess file if there will be less than 1001 users per minute.

You can add in htaccess generator your public IP address, or address of the server to leave open access.
