How We Use Cookies

Our website, like many others, stores and retrieves information on your browser using cookies. This information is used to make the site work as you expect it to. It is not personally identifiable to you, but it can be used to give you a more personalised web experience.

Types of Cookies

First Party Cookies

One of the key attributes of a cookie is its 'Host' - this is the domain name of the site that ultimately sets the cookie, and therefore is retrieved by on a subsequent visit.

If the host name is the same as the domain in the browser address bar when it is set or retrieved, then it is a First Party Cookie.

Third Party Cookies

If the host domain for a cookie is different to the one in the browser bar when it was downloaded, then it is a third party cookie.

These are typically used by advertising networks which display adverts in multiple sites. Whenever you visit a site displaying that company's adverts, their cookies are set and retrieved from the browser. In this way the advertiser can 'track' the websites visited by that browser - and by inference build up an understanding of what the person using the browser is interested in.

Session Cookies

Session Cookies are only stored temporarily in the browser's memory, and are destroyed when it is closed, although they will survive navigating away from the website they came from.

If you have to login to a website every time you open your browser and visit it - then it is using a session cookie to remember you.

Persistent Cookies

As the name suggests, this type of cookie is saved on your computer so that when you close it down and start it up again, it will still be there. All persistent cookies do have an expiry date, and if that expiry date is reached, it will be destroyed by the computer. If the expiry date is not set, or is in the past, then it is a session cookie.

However, there is no real limit on the expiry date - so it could be set to be 20 years in the future. In addition, if you revisit the website that served up the cookie, it will automatically place an updated version on your computer - with a revised future expiry date.

If you login into a website, then shut down your computer, start it up again, and go back to the website to find you are still logged in - then it is using a persistent cookie to remember you.

Persistent cookies are also used to track visitor behaviour as they move around a site, and this data is used to try and understand what people do and don't like about a site so it can be improved. This practice is known as Web Analytics. Since Google started providing its own analytics technology free of charge to website owners, almost all websites use some form of it - although there are also paid-for services available to rival Google's.

Analytics cookies are probably the most common form of persistent cookies in use today.

Secure Cookies

Secure cookies are only transmitted via HTTPS - which you will typically find in the checkout pages of online shopping sites.

This ensures that any data in the cookie will be encrypted as it passes between the website and the browser.

HTTPOnly Cookies

When a cookie has an HTTPOnly attribute set, the browser will prevent any client script in the page (like JavaScript) from accessing the contents of the cookie.

This protects it from cross-site-scripting (XSS) attacks, where a malicious script tries to send the content of a cookie to a third party website.
