My company is currently offering "web forwarding" to our customers for free, but this service outsourced to the same third-party that provides our DNS hosting. While the DNS service is rock solid, the redirection service has had many shortcomings including delays in updating redirects, caching issues, etc.

This was one of a few ideas we had for bringing this in-house. I've seen other DNS-configured redirection services, but nothing with the flexibility we'd need to offer our customers to match what they're currently getting. I thought I'd do a quick mock-up of the idea and put it out there to get some feedback.
