Issue

X-Magento-Vary cookie is set incorrectly for logged-in customers that belong to the same customer segment, causing improper caching for some pages.

Prerequisites:

Adobe Commerce Inventory Management (MSI) modules are installed and enabled.

Steps to reproduce:

  1. Configure Varnish or Fastly cache.
  2. Create a new customer segment and assign it to the Registered customers.
  3. Create two customers, e.g., customer1 and customer2.
  4. Clear the cache.
  5. Sign in as customer1 and go to the home page.
  6. Open an incognito page on your browser.
  7. Go to any page other than the home page.
  8. Log in as customer2.
  9. Go to the home page.
  10. Check if the page is cached in the browser dev console.

Expected results:

The page is retrieved from the cache.

Actual results:

The page is not cached.
