Unfortunately, its not that simple... Its not because parameters are  
not supported, but because search engines have troubles to deal with  
them. If you use parameters the search engine cannot uniquely identify  
a page because URLs to the same page are always different (even inside  
the same session links to the same page always have a different URL  
because of the callback keys). If you look at http://www.google.ch/search?q=useful+site%3Aseaside.st 
  you see that the Trivia page occurs twice, even though Google is  
hiding similar pages (if you make it show all results you get a lot  
more duplicate entries).

This is problematic, not only because search results show up multiple  
times, but also because
- having multiple URLs can dilute link popularity [1]
- Google may penalize the ranking of sites with duplicate content [2]

If you cannot get rid of the parameters I think that what Lukas  
suggested earlier in the thread makes sense (that is, provide a  
sitemap and use webmaster tools to hide parameters).

Cheers,
Adrian
