I am a bit of a novice on web hosting - We have built a site in Flex that is delivered on a SaaS basis. We have put a dedicated system for a client on a URL of their choosing (purchased through Go-Daddy) and have put a simple forward with Masking on the site. This works fine but in the view source on the browser, it shows the IP address which is obviously a security issue. I have tried changing the IP in the DNS to the IP the site is located at on our server but as we use a sub-IP (i.e. 10.10.100.100:1000), it won't accept it.
Any ideas?
Looks like you want to install a reverse proxy. My understanding of your case is that there's a browser A using your clients site B which either pulls in resources or accesses in some other way from server C. Ypu want to hide all references to server C, so that it looks like B is stand-alone. configure your web server on B to act as a reverse proxy to C for a specific set of resources.
