Rewrite for inline anchor

[eluser]hykoh[/eluser]
I'm using language/index.php rewriting .. my URI's are actually looking like this:

Code:

http://www.example.com/en/controller/function

Now i tried to set an internal anchor

Code:

<a href="#xxx">Go to Category XXX</a>

Code:

<a name="xxx">Category XXX</a>

but if i click on the first anchor, it forward me like a "real" link.

How can i reply all href urls beginning with # ?
