[TYPO3] extend caching by a variable (like pi_autoCacheFields)

[christian oettinger]

Hi List,

I desperately need some help, I'm stuck.
If I wanted to extend caching for typo3-pages by a variable of my own 
extension (so that depending on that variable multiple "page 
impressions" are cached for one page) I'd do like this:

        $this->pi_autoCacheEn = 1;
        $this->pi_autoCacheFields = array (
            'tx_oebooksandmagazines_pi1[showUid]' => array ('list' => 
array (0,1)),
        );

In that standard scenario

Now I want to do the same for Variable "real_uid" (which is created by 
typo3-Menu with overrideId). For "real_uid" is not a pi-var I obviously 
can not use the functions above (I tried).

How can I do this?


I'm really grateful for any hint!
