[TYPO3-english] RealURL redirect on multidomain site

[Vladimir Kubak]

Hi,
we have multidomain site. When on some domain I have a menu from other 
domain and that menu contains a page of type External URL, clicking to 
that link in FE doesn't work properly. Instead of redirecting to given 
external URL it shows this External URL type page as if it was standard 
TYPO3 page (!). When there are no different domains involved, everything 
works fine.
Could it be the problem with RealURL, TYPO3 Core or maybe our Apache config?
Using TYPO3 4.4.7, RealURL 1.10.2, Apache 2.2 on SUSE.
Thanks for any help.
