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, |
