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
