Joomla Wrapper and redirection

I am using joomla and a script called Olate Download for my site. So I have made olate to display in a joomla wrapper.

what i want to know is how to redirect the olate pages to the joomla wrapper. the pages when indexed in google etc are linked directly to the olate without the wrapper. so what i would like to do is redirect all the incoming olate links to the joomla wrapper ( i understand it will be same page) but also want the search engines to index the olate pages without any problems.

i think this can be done using htaccess. so someone please tell me how to create such a rule. it should redirect all the users which is not reffered from my site to the joomla wrapper except search engine spiders.


thank you very much..
