Technology Brief
Cookies
Category: Site Elements
Cookies are small text files that web servers may place on a visitors computer in order to store some information, often used for state information. The W3Techs web robot never tries to submit information to a website (e.g. login information), and therefore does not detect cookies which are defined in those transactions.
