In IIS, a binding specifies how incoming connections to a web server should be handled.
A binding is a combination of a protocol (HTTP, HTTPS, and so on), an IP address, TCP/IP port, and host name. The binding thus tells Windows and IIS how to route requests inbound to your system.
Bindings allow you to run more than one website on a single host. There are a few ways to do this:
- Configure multiple IP addresses and create a binding for each IP address to a different website
- Configure a single IP addresses and multiple ports and point each to a different website
- Configure a single address and use the host header option that routes requests for a given write on the host.
If you use the multiple IP address option, you need to configure multiple IP addresses on the system and ensure that the DNS entries for each website point to the correct IP address. This approach requires extra overhead and uses more IP addresses.
Using a single IP address and multiple ports saves on IP addresses...
