Introduction

Filtering mechanism

The smart filtering mechanism enables the powercache to block any unwanted contents in many ways.

Simple pattern

The host name can be compared using a simple pattern. A "*" (a star character) stands for any number of any character.

As an example:

 

"*.foobar.com" matches any sub domain of foobar.com, such as www.foobar.com or img.foobar.com

 

Regular expression

 

Ultimately you can use regular expressions (also known as regexp).

While they can be quite complex, they provide a very powerful comparison method.

 

Describing regexp can be easily found on the Internet.
