GrowthBook Users

Hi Gareth, you can do something similar with GrowthBook with a custom header

when a user is assigned, there is a tracking callback fired

and you can add any custom code there to set headers

or anything else to make sure the cache is aware of the experiment

Or, as you say, you can run GrowthBook on Varish or on any edge

Hey <@U01T6HCHD0A> thanks for this I really appreciate the assistance
