Hosting websites with different portnumbers in ASP.Net IIS server

I have just begin using ASP.Net Web application in Visual Studio. What I want to know is that I have two web pages namely index1.aspx and index2.aspx. I want to host them separately using different port numbers in local host on the iis server. I know site binding is used in these cases but not sure how to go about it. What is the best way to do this? I want them to run simultaneously and communicate between each other.
