Cacheable pages are not properly stored or served from the Fastly cache, resulting in inconsistent caching behavior and reduced performance.
Steps to reproduce:
- Enable the Fastly cache.
- Create a new website/store/store view.
- Add the secondary website code to
index.php:
$_SERVER['MAGE_RUN_TYPE'] = 'website';
$_SERVER['MAGE_RUN_CODE'] = 'web2';
- Check cache control header using curl:
curl -Is https://localhost/m247/pub/ | grep cache-control
Expected results:
Cacheable pages are cached in Fastly.
Actual results:
Cacheable pages are not cached in Fastly, the max-age=0 returned in the header.
curl -Is https://localhost/m24develop/pub/ |grep cache-control
cache-control: max-age=0, must-revalidate, no-cache, no-store
