Description
When release managers use the website admin interface to create or modify Release pages, a handy "View On Site" button is available on the input page that allows you to preview the updated release page. As of a recent website update, clicking the "View on Site" button still takes you to a rendered preview page, however changes often are not reflected. This appears to be due to the preview rendering not causing the CDN to be purged so you continue to see an outdated version which is very confusing. Manually sending a PURGE request to the CDN causes the updated page to be shown. While I cannot be 100% certain, I believe that this problem did not exist prior to a recent upgrade (otherwise I would have complained about it before because it is very annoying until you remember what the problem is!). When editing Page objects, which have a similar preview feature, it does appear that the CDN cache is flushed for them as the changes seem to reliably render. So perhaps some change got lost in the website upgrade?
