Welcome to the CodeIgniter forums!

It depends what you mean. If you explain why you think you need to use query strings, and why you don't want to, that would be useful.

Can you give us examples of current undesired link and new link format that you'd like to use and we'll see if we can figure it out?

If I understand you correctly, the simplest solution would be to use the category and product IDs in the URL.

yoursite.tld/categories/view/<category_id>[/<page_num>]
yoursite.tld/products/view/<product_id>
yoursite.tld/cart/add/<product_id>

Is there any reason that won't work for you?
