Caches the rendered contents of the body of this macro. 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 will be refreshed if the body of the macro changes or if attachments to this page have been 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.
