I'm adding a shopping cart to a new website and i'll have to use cookies so that I'm not passing variables around the url. Anyhow since I'm using cookies (and they're required for users to add things to the shopping cart) I'll use some php to redirect anything that doesn't allow cookies to a page which says cookies are required. Any idea if this is a problem for the search engines? My home page wouldn't require cookies, so hopefully this isn't considered cloaking. Anyhow any ideas or thoughts on this subject would be great.
As long as the pages are accessible without cookies, there isn't a problem. Only use the cookies for storing the information on what people want to buy, not too much else.
All of the pages are accessible without cookies except the shopping cart. Attempting to access the shopping cart without cookies will redirect you to a page which informs you that cookies must be enabled to use the shopping cart.
