====== Important Notes for FoxyCart Users ======

===== Know Your Gateway =====
Because e-commerce involves so many moving parts, problems and incompatibilities //can// happen. The biggest source of frustration can be incorrect understanding or expectations with regard to your payment gateway. Please read the [[..:docs:paymentgateways|Payment Gateway Notes]] for critically important information regarding returning users, subscriptions, and limitations your gateway might be imposing on your transactions.

===== Browser Limitations, and What They Mean To You =====
==== Internet Explorer and Big Forms ====
Internet Explorer (all versions through 8) have a limitation on the amount of data that they can accept in the URL. Since you're passing information back and forth from your site to your FoxyCart cart every time a user adds something to the cart, this can create problems if you use very large forms.

**If you //are// using large "add to cart" forms**, you have a few options:
  - Do not use the standard "foxybox" (Thickbox) cart. Instead, load the cart on a new window.
  - Attempt a workaround. More info on [[http://forum.foxycart.com/comments.php?DiscussionID=1483|this forum thread]].
