Oh dear. Thought you were spoofing them, until I clicked through.

I set out my take on this 'what is DNT' question in an article I wrote - http://www.kemplittle.com/publications/item.aspx?ListName=KL...

It's a bit heavier going that the DDG approach, and more euro-centric, but hopefully gives a decent understanding.

Any feedback or comments encouraged.

The law states: "a person shall not store or gain access to information stored, in the terminal equipment of a subscriber or user unless the requirements of paragraph (2) are met."

Paragraph 2 then sets out how consent needs to be obtained, and the test that the subscriber needs to have given their consent before information is stored on their computer.

Cookies, flash cookies, HTML5 databases, etc. are all covered under the general concept of storing on a subscriber's computer.

The original law is here - http://www.legislation.gov.uk/uksi/2003/2426/regulation/6/ma... - and here are the recent amendments - http://www.legislation.gov.uk/uksi/2011/1208/made

Isn't this vague enough that a site with an image is infringing?

"Sure, they requested the web site, but they never explicitly said they wanted the image, and now you've gone and stored it in their cache."

How do you read back the tracking information from a cached object, page or image without replacing it with a fresh new one?
