[TYPO3] link between domains problem

[Klaus Hinum]

hi group

i use two different page-trees for different subdomains.
when i want to link between the subdomains, i use the "external URL" 
feature of the RTE. Since Typo3 4.0 the domain name is capped and the 
links does not work anymore.

e.g.

on test.abc.com a link to http://www.abc.com/123.html
is getting
123.html in the output and therefore linking to 
http://test.abc.com/123.html -> wrong

please help!

regards klaus
