The prerendering cache or Prerendered Cache is a DB cache that is available for:
- Items : table
- Comments : table
- Private Messages : table
Note: Rendering plugins are encouraged to pre-render as much as possible, but in some cases, the rendering can only be done accurately at display time. This means that the prerendering cache does not contain final content ready to be displayed. An extra pass of rendering is possible at display-time.
Pre-rendering occurs on demand, at display-time, if the requested Item/Comment/Message has an empty cache.
The pre-rendering cache is emptied for a specific Item whenever that Item is saved with changes.
In the case of Content Blocks, this pre-rendering cache invalidation can be recursive.
The cache can be manually cleared through the Tools Tab.
