AdBlock

The AdBlock checker allows you to determine whether a user makes use of AdBlock. To determine whether this is the case, you will see that Harvest tries to load the file . As soon as this tool loads, we check whether we already checked for AdBlock, if not, we initiate the value for hasAdBlock in the session meta cookie to “Initial”.

In parallel the file will be requested. If it is blocked, we update the hasAdBlock value to “1” otherwise to “0”.

Every event the value from the Harvest Session Meta cookie will be added to the event, this makes sure that for each event you know whether the user used AdBlock or not.

How frequent is AdBlock checked?

We store the result of the check in the session meta cookie. This means that we check for AdBlock each session.

For more information about sessions, read our sessions management documentation.
