Consent

Usually needed

_hjSessionTooLarge is in the Functional category. Functional cookies usually need the visitor's consent, unless the cookie is strictly necessary for something the visitor asked for, such as remembering a language they just chose.

GDPR and ePrivacy (EU): Consent is needed before setting _hjSessionTooLarge, unless it is strictly necessary for a feature the visitor asked for, such as remembering a language they just chose.
UK GDPR and PECR: The same as in the EU: consent first, unless the cookie qualifies for the strictly necessary exemption.

Managing _hjSessionTooLarge with a consent banner

A consent banner can keep the script that sets _hjSessionTooLarge waiting until the visitor accepts functional cookies. Kukie.io's cookie scanner finds _hjSessionTooLarge and sorts it into a category. The banner holds back known trackers by default, and any other script you tag with its category waits too.
