Is it possible to determine if the current request for a given site is actually from a domain setup to forward with masking? I've tried the following but they all return information about the 'actual' URL:
- Request.Url.DnsSafeHost
- Request.Url.AbsolutePath
- Request.Url.AbsoluteUri
- Request.Url.Host
- Request.Url.OriginalString
Thanks.
