TYPO3 Core

Sometimes a page has many same links, for example list view for a product could has links from a preview image, from a title and a teaser description, all links going to detailed view of a product and all links has the same typoscript config.

In such cases typoLink() function can benefit from inner cache – if typolink config has same md5 from serialized config, then url and tag params is not being calculated again (it is rather big function) but retrieved from cache.

Content being placed inside A tag of course not cached, only tag.

Such cache is essential when TS-templates are heavy used - if php code in plugin is involved only in data preparing and all rendering being done in template then we have to call typolink many times with same config or to use ugly workaround "caching" with help of LOAD_REGISTER
