Hi DW,
It seems that the product link from the cart differs from the actual product url.
We have solution where the product URL looks like this: https://goecker.dk/epson-surecolor-sc-p700-a3-printer
However when you go back to the product from the cart
The URL ends up using the full URL, like this: https://goecker.dk/detalje/workflow/printere/epson-surecolor-sc-p700-a3-printer
I have tested it on a demo swift aswell, where I get similar results.
This product: http://smartpage.swift.dwdemo.dynamicweb-cms.com/e-bikes/e-mountain-bikes/e-big-tour-400eq/s
Becomes this: http://smartpage.swift.dwdemo.dynamicweb-cms.com/special?productid=6110866994M&variantid=VO12
When you access it from the cart.
Im not sure whats causing it, but it would be preferable to keep the same URLs no matter where you access the products from.
