We recently upgraded to CF11 from CF9 and have ran into a challenge. I understand this is probably very fundamental but I am at a loss to figure it out because our cart worked so well for years before. I pass a url variable to the cart containing the sku number and it populates my preorder table with a quantity of one unless I also pass the quantity variable in the same string at which I use if isdefined to detect. My cart works but upon page refresh or if the back button is hit, it will increment one to the quantity field. Can someone tell me the way to eliminate this issue? In the address box of the old cart we hid the variable in the url string when passing the call to the cart but the same code not with CF11 does indeed show the variable(sku) in the url which is passed causing the cart to update. Looking for help here please?
Thanks
