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

Information Security

  • The same version of a cached page will be shown to all users, so this should not be enabled on pages that present custom views to individual users (for example, query results affected by user permissions).
  • The page cache process occurs after permissions checks are performed by Confluence, so page-level view restrictions are respected.
