To add a cache tag, go to Admin Tools > CMS Configuration > Cache Manager. On the left column you can see any currently added cache tags. To add new tags, click the ti ti-circle-plus button at the bottom of the grid. When adding a cache tag, the tag name should be as short and descriptive as possible. We highly recommend using the Description field to describe the purpose of the cache tag in detail. You’ll want to be careful, as cache tags cannot be removed or modified. Also, keep in mind that tag names must be all lowercase without any spaces.
