Cookies and Cookie Types
Cookies are small text files that are stored on your computer by websites you visit. They allow the website to do things such as keep track of your preferences as you move around the site so that we can personalise pages for you and store little bits of information about your visit so these can be stored for your future visits. Cookies stay on your computer for varying amounts of time depending on their type and the parameters the website sets whilst creating them.
Cookies come in three different types. The cookies themselves vary very little between the types but their effect and use is different.
First Party Cookies
First party cookies are created by the website you are visiting. They can only be read and used by that website.
Third Party Cookies
Third party cookies are not set by the website you are visiting. They are set by a different organisation whose features are being used by the website you are visiting. This is common practice if sites use analytical systems supplied by a third party (as most are) to track the usage and load on their website. These may also be created by embedded content in the web page, a YouTube video for instance, as these need their own cookies to work.
These enable a website to track your use throughout the site, storing choices you have made and any information you have provided. They are a type of first party cookie that only remain stored on your computer until you close your browser when they are then deleted.
