How is chosen which variation a user gets to see? Is a request to the Matomo server needed?
No request to the Matomo (Piwik) server is needed in order to pick which variation a user will see.When a user enters your experiment for the first time, a variation is randomly chosen within the browser (JavaScript). On subsequent visits, the visitor will get to see the same variation as we persist the name of the chosen variation in the browser.
