What am I talking about? Well, due to an amendment to the law (the Privacy and Electronic Communications (EC Directive) Regulations 2003, and the new Directive 2009/136/EC) in May last year, the way information is stored by technology is being changed, and primarily how cookies should and can be used and stored - hence the nick-name for this amendment: "The Cookie Law".
The UK government has given businesses a year to comply with the changes,
which means that as from May 2012, any organisation that does business in the UK
(and EU) is affected.

Just so you don't panic too much, this doesn't appear to affect intranets!
It only applies to public-facing websites.
