1. Parameters Declaration: The parameters block defines a single parameter named param1. This parameter is a string with a default value of 'example-value'. It’s used to customize the HTTP request URL.
2. Stages Declaration: Inside the stages block, you have one stage named ‘HTTP Request’.
3. HTTP Request Stage: Within the ‘HTTP Request’ stage, you have a steps block containing a script block. This is where the actual steps of the stage are defined.
   • Script Block: Inside the script block, you’re making an HTTP GET request using the httpRequest step. The URL includes the value of the param1 parameter as a query parameter.
   • Response Handling: The response from the HTTP request is stored in the response variable. The script then writes the response content to a file named response.txt using the writeFile step.
   • Print Statements: The script also prints out the status, response content, and headers of the HTTP response using println
