Introduction - Sticky 1st Party Cookie

Prefixbox uses a user based, 1st party cookie (_prefixboxIntegrationVariant) which contains the value indicating whether the user is on A (‘control’) or B (‘treatment’) version of the experiment. This cookie is “sticky” which means that a particular user sees the same version during the whole period of the test.
