[TYPO3-mvc] realurl fixedPostVars not cached?

[Bas van der Togt]

Hello,

A few weeks ago i build an extbase (6.0.0) plugin and it was working 
great but very slow. Today i found the problem.

I found a strange bahaviour in realurl (1.12.3). When i put my realurl 
table configuration in the fixedPostVars section my plugin is not 
cached. When i move the configuration to the postVarSets section all 
pages are cached correctly and my plugin is very fast! Is this a bug or 
what? I like fixedPostVars more because than i have nice and clean urls.

Kind regards,
Bas
