I've been asked by a client to help with an IIS 7 issue. We have a server running Windows server 2008 and IIS 7. There are currently 2 applications being hosted within IIS 7 and both are located under the "Default Website". Until now, these applications have been used by the developers and they've been accessing each site independtly by IP (ex: http://someIPaddress/directorytosite1
These developers are now wanting me to configure public dns to route by name. They want web visitors to browse directly without having to use the "/subdirectory". We've registered 2 different dns names and now I'm trying to work through how to configure IIS to properly route incoming traffic. The developers are telling me that I should be able to do it outside of IIS (like at our dns hoster), but I'm thinking IIS will need to know how/where to send incoming requests.
What would be the best method for accomplishing my goals considering both of these sites are located within the Default Website?
I know nothing about their applications, so I want to make sure any changes I make are safe and won't cause issues.
