The Web Server role is used to configure Security Center Web Client, a web application that gives users remote access to Security Center. Each role created defines a unique web address (URL) that users enter in their web browser to log on to Web Client and access information from Security Center.
Multiple instances of the Web Server role are permitted. You might create one role for local users and a different role for remote users, who access the Security Center network over the Internet.
It is recommended to deploy roles on separate expansion servers.
Each role must have a unique URL. The URL format is https://computer host name or IP address:port/webAddress.
If multiple roles are created on the same server, they must each use a different HTTPS port or web address. Otherwise, the role entity turns yellow and an Entity warning event is generated.
The defaults are HTTP port 80 and HTTPS port 443.
