[TYPO3-ttnews] Mutiple Domains internal link

[Andreas Wengrzik]

hey list!

i´ve got a problem...
I have two domains with the same typo3 backend the only thing changes by 
domain is the stylesheet.

Now i want to create a link to

index.php?id=7&tx_lzgallery_pi1[showUid]=500

So, if i make the link llike
http://domain1.de/index.php?id=7&tx_lzgallery_pi1[showUid]=500

The style changes if the user is logged in to domain2 - even the user 
isnt logged in cause of cookie for domain2

Any ideas what to do to make it work?
A way with typo3 or do i need some kind of mod_rewrite??

Thanks!
bye
