Feature: #22439 - Allow nested GET-params in config.linkVars
============================================================
See :issue:`22439`
Description
===========
TypoScript setting :typoscript:`config.linkVars` configures which parameters should be passed on with links in TYPO3.
It is now possible to specify nested GET parameters there.
Example:
.. code-block:: typoscript
config.linkVars = L(0-2),tracking|green(0-5)
With the above configuration the following example GET parameters will be kept:
&L=1&tracking[green]=3
But a get parameter like tracking[blue] will not be kept.
The value constraint in round brackets works in the same way as for not nested GET parameters.
