Final answer:
To judge if a remote server is running IIS or Apache, you can check the response headers, use online tools, or check the domain's DNS records.
Step-by-step explanation:
In order to judge if a remote server is running IIS or Apache, you can use different methods. One common method is to check the response headers of the server. For example, if the response header includes "Server: Microsoft-IIS/", it indicates that the server is running IIS. On the other hand, if the response header includes "Server: Apache/", it indicates that the server is running Apache.
Another method is to use online tools or services that can detect the type of server running on a remote host. These tools analyze the server's response and provide details about the server software being used.
Finally, if you have access to the domain's DNS records, you can check if the server's IP address is associated with a known hosting provider that primarily uses IIS or Apache.
