Hotjar is a behavior analytics tool that helps site owners understand how visitors use their site through heatmaps, session recordings, surveys, and feedback widgets.
_hjTLDTest
When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed.
