For some unfathomable reason it seems since the 48th week of 2021 we are getting a _mkto_trk_http cookie instead of a _mkto_trk . O other cookies do not have a _http postfix. Both client and server side shows this consistently. I am nonplussed. Did anyone else see the same? Is this a setting in Marketo maybe ?
Solved! Go to Solution.
Yet it's completely undocumented , https://nation.marketo.com/t5/knowledgebase/browser-cookie-updates-how-marketo-munchkin-is-affected/... has nothing on this.
