What are cookies?

Cookies are small files that are downloaded onto your computer when you visit a website. They are used by many websites to make them work, or to help them work more efficiently. They also provide us with information about how you use the website.

Types of cookie

The LSE website is a large and complex service comprising various sub-sites. Various cookies are in use across the LSE website, with the cookies in use subject to changes as the website develops. The following table details the cookies used on the LSE website following our latest audit (May 2018).

Session cookies allow you to proceed from webpage to webpage quickly and easily so you don’t get asked for the same information you’ve already given to the site. The cookie is then automatically deleted when you leave the website.
