To fix Redirect Loop issues for Location sub domains on OxyClassifieds when hosted through CDN

I need help in fixing Redirect Loop issues for Location sub domains on OxyClassifieds when hosted through CDN (edgecast cdn). When opening running website directly from server works normally, when running through CDN it gives Redirect Loop error. Google Chrome says : This webpage has a redirect loop Firefox says : The page isn't redirecting properly Only people who have good knowledge on mod_rewrite, and CDN can fix this I think. Thank you.
