Servebolt Optmizer v3.5.21

The release performs 1 specific task, which only helps accelerated domains customers.

What it does is add a Cache-Tag header “search” for search results so that they can be purged when there is a content update. This only works for Accelerated Domains purging, where as Servebolt CDN does not allow for caching of the search.

In the short term we’ll be adding support for this into the ACD worker, so that search results can be cached until there are any changed on the site. Important to note its a “can” and not the default setting.   There will be documentation how to do this when we update the Worker.
