Final word on the cookie topic (until the next time...): this is a straight repost of the guidance from the UK Information Commissioners' Office summarising cookie controls by major browser and some additional information on controlling and opting-out of cookie placement. RC
What are cookies?A cookie is a small file of letters and numbers that is downloaded on to your computer when you visit a website. Cookies are used by many websites and can do a number of things, eg remembering your preferences, recording what you have put in your shopping basket, and counting the number of people looking at a website.
The rules on cookies are covered by the Privacy and Electronic Communications Regulations. The Regulations also cover similar technologies for storing information, e.g. Flash cookies. The Regulations were revised in 2011, and the ICO is responsible for enforcing these rules.
How do the cookie regulations affect me?You may come across information about cookies on websites and be given choices about how some cookies are used. This might include, for example, being asked to agree to a cookie being used for a particular service, such as remembering your preferences on a site.
