Guest cache not redirecting default URL's properly

[tavenger5]

I noticed a serious problem with URL redirection when the guest cache is enabled. The translated URL's are not redirected properly.

Here is how to reproduce:

1. Enable guest cache
2. log out of your site
3. go to a default URL, for example: http://www.vbenterprisetranslator.co...ted-pages.html
4. Click on a translated URL, for example: http://www.vbenterprisetranslator.co...ladzijden.html
5. Click back on the default URL
6. The result will be something like http://www.vbenterprisetranslator.co...ladzijden.html
   when it should be http://www.vbenterprisetranslator.co...ted-pages.html

This behavior will not happen when guest cache is turned off. This is creating a whole lot of duplicate URL's for default pages.
