Such a file can contain information that is needed for identification purposes and for the browser session to run more smoothly and more. By definition, a text file that can associate and report a recipient’s activity is spyware. Organizations should address the matter in the formation of security policies.

The infrastructure owner must decide whether cookies should be enabled to allow the writing of these special tracking files or disabled to block them.
