Good Old HTTP Test on Windows with VBScript

Deploying a Point-Of-Sale system on a large store with existing security protocols is not a walk in the park. Processes that can be easily done in a test environment can be prohibitive in the actual production setup. ( TL;DR Scroll further down for the script)

Scenario You are implementing a new electronic payment system in store ABC. Hardware replacement went well, installation went well, then its time to test. That easy, just run a few transactions and you will be out of the site in no time. Then it hits, the PINPad system had an issue downloading the configuration file from the server across the internet.

It would be a learning experience but it might end up consuming a lot of time.

Why reinvent the wheel? So I started querying the internet for a better solution. I stumbled upon Stateless
