Fallback Host based on URL

We host a site that provides downloads to a variety of other sites, and we currently have a profile that implements a Fallback Host when the nodes are overloaded. However we now have a problem that when a download is requested from a site that sub-contracts us for download services, we redirect to our site as a fallback host when we should redirect to theirs. This has caused some of the sites that we provide download services some distress.

 

 

Is there a way to dynamically set the fallback host based on either the URI or the referer if the fallback host condition is triggered?
