The presentation of a page stored in memory.
The first time a page or blogpost is viewed, normal rendering occurs and the resulting HTML is saved in a memory cache. Subsequent requests for that page are serviced from this cache, bypassing the entire rendering process.
The cached version of a page is discarded when:
- the page is edited
- an attachment is added, updated, or removed
- a label is added or removed
- a comment is added, updated, or removed
- page-level restrictions are changed
- the Instant Page Cache Cleaner job runs
