Return to htaccess

Sad but true: There often comes a time when the "open" nature of internet becomes a problem. This can be by accident (a badly behaving robot) or on purpose (someone attacking a banner network). In either case, the first level response is the same: block access with your .htacccess file :-).

This isn't meant to be a full fledged tutorial, but a quick example of the more common needs.

The most common scenario is where you want everyone except a few visitors to be able to get to your site. Your .htaccess file would start like this:

	order allow,deny
	allow from all

Then you follow that with lines to specify the addresses that you want to block:

	deny from 192.168.128.14

	deny from 192.168.128.

	deny from somehost.example.com

	deny from .example.com
