Affiliate Link Shortening

We are looking to build an affiliate link generating platform for short URL's. These shortened URL's would create affiliate links when the original URL is to a product from any of our supported vendors, but NOT over ride existing affiliate links that are being shortened. Technology examples: [login to view URL] [login to view URL] They key difference between between the above technology examples and what we are hoping to accomplish is that we want to use this affiliated link system for short URL's instead of for publisher content. Important Notes: Please list EXACT affiliate portals that your solution will work with out of the box, but it MUST include: - Commission Junction - Linkshare - PepperJam - Google Affiliate Network - Amazon Associate Do not worry very much about the UI of this technology as we will be integrating this technology into an existing site and template.
