Phorm copies your pages in transmission, and creates a derivative work ('a user profile').

A copyright owner has the exclusive right to copy a creative work, and create derivatives. Where unlicenced copies are made, you may invoice Phorming ISPs for substantial royalty payments. And you set the price, not ISPs.

Expect £10, £100+ per page impression, according to the value of your work, and the disregard shown for your rights by Phorm.

The Javascript Tripwire test uses client side javascript to analyse cookies.

If Phorm cookies are detected, the browser can be redirected to a page you specify.

Tested on FF2, IE7, Opera 9, FF3 beta.

Pros; requires no server side code at all

Cons; requires client side scripting

Try the code on this page.

The Dephormation Speed Trap test uses a slow web page to test the speed of response from the server using AJAX (Javascript).

If the server responds too quickly with a redirect, you know Phorm have intercepted your page.

Pros; likely to reliably detect any redirect

Cons; requires complex client side script

Try the code without redirects, and with redirects.

The Cookie Test examines the characteristics of the cookies sent by the client browser to a non-standard http port.

If Phorm's UID cookie is present, or the user is a customer of BT or Virgin Media, the test displays a colour coded warning message.

Pros; entirely server side, simple code

Cons; requires PHP and a second port

Test your own connection

If Phorm's UID cookie is present, the server side code can be written to check.

Pros; simple code on client and server

Cons; requires PHP on server
