[TYPO3] Content redirect /switching depending of query string parameter

[Gos'n Prirodni]

Hi all,

I have a problem: I need to select wihich part of the page / content
elements will be shown depending of some query string parameter.

Is that possible? Maybe I can somehow change the vsibility of the content
elements or diplay content of some other pages depending of the query string
parameters.
