URL-parameter-based navigation using Spring Webflow

as far as you probably know 99.9% of e-shops need their products to be indexed by search engines. I don't know any way to have indexed site except using URL parameters. Now I'm writing the e-shop with usage of Spring Webflow (SWF), and after a lot of googling I have no clue how to do parameter-based navigation with SWF. Also it's worth to say that I use JSF2 with SWF.

Can somebody explain me, please? Is it at least possible with SWF?
