[TYPO3] cache problem?

[PEF]

Hey,

I've made a menu using a fakemenu-script that adds a cid-param to the 
url. The problem is, that even though the cid-param is changing in the 
url, the cid-param doesn't affect the other items on the page. The 
id-param and the L-param works okay. If I press <ctrl><F5> everything 
fall into place.

Something tells me, that it's a caching problem.

url: http://www.mydomian.dk/index.php?id=18&L=1&cid=3

If I change it to ....&cid=4 links on the page still says ...&cid=3
Pressing <ctrl><F5> and links says ...&cid=4

Anyone who has a solution?
