0 JavaScript Global Variables

These are the non-standard "global" variables defined on the window object. These can be helpful in identifying possible client-side frameworks and code.

0 Cookies

Cookies are little pieces of information stored in the browser of a user. Whenever a user visits the site again, he will also send his cookie values, thus allowing the website to re-identify him even if he changed locations. This is how permanent logins work.

2 Console Messages

A page may trigger messages to the console to be logged. These are often error messages about being unable to load a resource or execute a piece of JavaScript. Sometimes they also provide insight into the technology behind a website.
