What is a Cookie?

A cookie is a small text file that can store small bits of data on your computer.

What are they used for?

Generally cookies are used to enable the website to function correctly, by storing where you are in a particular transaction or part of the site, so that the next page you visit can be tailored to your needs. However they are also used for other purposes like performance analysis, website statistics and advertising targeting. Here is a breakdown of the common classifications:

1) Strictly necessary
These cookies are essential to enable the website to function, for you to navigate. Without these you will not be able to use the site. For example a shopping cart would not function without these.

2) Functional cookies
These log information about options you may have selected and enable a website to tailor the information presented to you in a more personalised way.
The cookies might also include flash cookies – which can be set using this link here: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html

3) Performance cookies

Its used in reporting data and helps the website owner design, measure and optimise their pages for the best user experience. The website owner may share this data with 3rd parties who they may outsource the analysis and benchmarking to. Generally all this data is anonymous and not identifiable to you.
