Types of cookies

• First and third-party cookies: whether a cookie is 'first' or 'third' party refers to the domain placing the cookie. First-party cookies are those set by a website that is being visited by the user at the time (e.g. cookies placed by www.opticalcomplaints.co.uk).
• Third-party cookies: are cookies that are set by a domain other than that of the site being visited by the user. If a user visits a website and another entity sets a cookie through that site this would be a third-party cookie.
• Persistent cookies: these cookies remain on a user's device for the period of time specified in the cookie. They are activated each time that the user visits the website that created that particular cookie.
• Session cookies: these cookies allow website operators to link the actions of a user during a browser session. A browser session starts when a user opens the browser window and finishes when they close the browser window. Session cookies are created temporarily. Once you close the browser, all session cookies are deleted.
