make a http trace request in ruby

To make a HTTP TRACE request in Ruby, you can use the Net::HTTP standard library. Here's an example:

main.rb
require 'net/http'

uri = URI('http://www.example.com/')
response = Net::HTTP.start(uri.host, uri.port) do |http|
  http.trace(uri.request_uri)
end

puts response.body
168 chars
9 lines

In this example, we first create a URI object representing the desired URL. We then start a new Net::HTTP session and use the trace method to issue a HTTP TRACE request to the server at the specified URI. The response object contains the HTTP response status code and headers, as well as the response body, which we print to the console in this example.
