[TYPO3] Handling parameters in RealUrl

[PEF]

Hey,

I am using RealUrl and I have a small problem handling a parameter. In 
my example, I have a parameter called "cat" for category. This cat 
parameter also determins a certain part of the menu - created as a 
fake-menu.

The menu part in question looks like this:
PRODUCTS
- Household
- Kitchen
- Toys

When clicking the menu item Household, the url says:
http://.../.../uk/household/products

But I want it to say:
http://.../.../uk/products/household

Same goes for Kitchen and Toys too.

I've tried to make some changes to localconf.php, but without any luck.

Regards
Peter
