rewrite forms GET data with htaccess
===

Sorry if is a dummy question but I don't really know how to get it to work the following issue
I have a form whats url after submission looks as it follows

    sites/example.php?category=Notebooks&prod_group=Apple&product=&customer_type=&voucher_type=

What I want is to rewrite this url on submit and the expected result should be 

    /folder/Notebooks/Apple
