    WEBrick is a Ruby library that makes it easy to build an HTTP server with Ruby. 
    It comes with most installations of Ruby by default (it’s part of the standard library), 
    so you can usually create a basic web/HTTP server with only several lines of code.
    
    The following code creates a generic WEBrick server on the local machine on port 1234,
