Google generates custom error when using netcat for banner information
I was writing an article on how to use HTTP to view web banner information. My first choice was to use the big G, Google.com. However, when I used the command nc google.com 80 and used OPTIONS / HTTP/1.1, Google generated this error message.
It is also interesting to observe how Google generates its logo using the color codes.
Following is the full code of this error message
