drupal_goto() uses a 302 redirect by default, which means a lot of redirects, including form redirects, get served with a 302 response code.
Having a issue in Varnish that is caching 302 response from user submitted forms for anonymous traffic.
It caches the first 302 redirect but then if the customer selects different options on the form it should be redirected to another url.
Not being able to cache product pages on our Drupal commerce site amounts to millions of cache misses a month and excessive performance issues. Drupal based page level caching is not a option as we have over 4,500 stores deployed.
How can this be fixed?
