Hello Kasper,

Thank you for precise ansewer. I will reflect about this point.

Let me kindley hint you in this occasion to a small vacancy in this 
exellent article, that is really an ey-opener upon caching.

I found no hint how the cHash is added to the link in practice. In the 
first edition of the "TYPO3-Handbuch from Galileo Press" that led me to 
the assumtion that it would be created under 2 mayor conditions 
automatically:

1. the use of USER-Object
2. the use of typolink-function

It is created automatically, but you need a third condition:

3. setting of useCacheHash-configuration for the typolink function or of 
cache=1 parameter for pi_link-functions respectively.

That information will hopfully run already into the second print of the 
book.

Best Regards

Elmar
