Alternative 301 redirect method?

Hey,

I want to redirect a product (using the wp-ecommerce plugin) straight to another page as soon as the user clicks on the product.

The issue I’m having is that I can’t run a 301 redirect from the htaccess filed because the specific file is not on the server (the directory isn’t on a server, it’s created on the go through a series of php links). It also isn’t a standard post, so I can’t use a plugin that does post and page redirects.

I also don’t want to use a 200 or 201 redirect because it is extremely unfriendly for the Search Engine.
