Rewriting a return from paypal

[jerry_louise]

I am just about finished writing a eshop where the user pays with paypal express. However paypal returns the following http://dev.mysite.com/products/returnexpress/?token=EC-41L012919E102253F&PayerID=54PTVYQXENJ7L

But my site has everything rewritten to http://dev.mysite.com/index.php?rt=$i where $i represents the class in this case products and the function which in this case is returnexpress.

Where this seems to be failing is the ? before the tolken, so how would i retrive the tolken from this url. Is it possible to change my htaccess to rewrite this request? And if so how would this be accomplished.

Better explanation ->

Hey there folks i am rather new to writing a .htaccess file and have only went as far to make it rewrite a route for my framework Cabbit.
Now it works for standard urls in my framwork such as http://mysite.com/controller/function/action however it falls on its bum when getting back the url from paypal(part of the framework is payments pro and express checkout) where the return is http://mysite.com/controller/function?token=thistokenfortheuser&PayerID=something
So i need it to come out as
http://mysite.com/controller/function/thistokenfortheuser/something

Also i am not sure if it is possible but it would be terrific for it to be possible that http://mysite.com/eshop/checkout is rewritten to https://mysite.com/eshop/checkout instead though as i said i don't know if this is possible and right now i can do it with php.

Thanks in advance for any help and suggestions.

current .htaccess
