[Typo3] Disable page cache of certain domains

[Robert John de Stigter]

Hi,
 
How can I disable typo3 to cache pages from a certain domain. For
example, part of the pagetree is only accessible via www.mydomain.com.
But back-end users who access typo3 use www.typo3domain.com/typo3/ and
when they use the View function sometimes links will be cached with the
typo3 domain, causing visitors to use that domain too. 
 
Cheers,
Robert
