Summary

Cache macro caches rendered data to improve page display performance.

This macro caches the rendered contents of its body. This is very useful when using macros that might be slow to render content, but where it does not really need to be dynamically generated for each and every request. Specifically, this can improve performance for accessing dynamic data from SQL, Excel, and similar macros. Cache is refreshed when the body of the macro changes or attachments to this page are added, removed, or have newer versions. The cache applies to all users that view the page. The cached content can optionally be indexed for Confluence search.

User specific content

Do not use the Cache macro around content that renders differently for different users. This is especially important for any content that is security sensitive.

Compatibility with other macros

See Interoperability.

Cache refresh

To force all Cache macros on a page to refresh, use the refresh request attribute with value true

From version 7.9.3, all Cache macros on all pages can be refreshed at the same time with the Expire cache parameter in the app's Configuration page. Contact your administrator to force the refresh for all pages and to know more, refer to the Configuration page.
- Example
```
http://localhost/display/DEMO/test?refresh=true
```
To force a specific Cache macro on a page to refresh, use refresh request attribute with value equal to the cache macro id. If not specified, it defaults to a sequence number based on position on page
- Example
```
http://localhost/display/DEMO/test?refresh=1

http://localhost/display/DEMO/test?refresh=myId
```
