self::ENV_VARYCOOKIE_DEFAULT always empty string for multi-store

[AJHopper]

Hi, We have a multi-store Magento 2 set-up and recently have noticed that we are getting issues with the LiteMage cache not working as intended for any site other than the main one.

in the "Model/CacheControl.php" file on line 352 it calls $this->request->get(self::ENV_VARYCOOKIE_DEFAULT)

This is always returning a correct value for the Main site, but always returning an empty string for any of the other sites we have.

Sorry for late reply. This means the vary cookie is not set properly. We haven't got any other reports like this. If you still have this issue, please create a ticket by email to [email protected] and provide more details for trouble shooting.
