Temporary Redirects

[AdagioWaterFeatures]

On my crawl report from SEOmoz, I have a lot of Temporary Redirects listed. The referring site is a product category page, but the URL listed is part of a shopping cart. For example:

| http://www.adagiowaterfeatures.com/cart.php?action=add&product_id=496 |

Tested true for a temporary redirect referred by this url:

| http://www.adagiowaterfeatures.com/categories.php?category=Free-Standing-Water-Features/Harmony-River-Collection |

Why does this occur and what can I do about it?

That likely means you're returning a 302 (temporary redirect) instead of a 301 (permanent). A 301 will transfer rank, a 302 will not.

I understand the redirect is wrong, but I didn't set up a redirect. I'm not sure why a shopping cart list would be a redirect from a product listing.
