# Feature: #22439 - Allow nested GET-params in config.linkVars {#feature-22439}

See [forge#22439](https://forge.typo3.org/issues/22439)

## Description {#description}

TypoScript setting `config.linkVars` configures which parameters should be passed on with links in TYPO3.
It is now possible to specify nested GET parameters there.

Example:

```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.
