Host

This is the internet address that this filter is designed to block.

You will need to spell it the same as the browser does. e.g. if you want to block a URL http://www.foo.com/annoying/picture.gif, then you should enter www.foo.com in the host box. You should not enter foo.com or 123.45.6.7, even if they represent the same site. The case doesn't matter.

You can paste a complete URL into here, and it will be broken up into the host and the exact or partial path.
