The simplest example to set a cookie is:

document.cookie = 'name=Flavio'

This will add a new cookie to the existing ones (it does not overwrite existing cookies)

The cookie value should be url encoded with encodeURIComponent(), to make sure it does not contain any whitespace, comma or semicolon which are not valid in cookie values.
