Create SimpleHTTPServer using Python

SimpleHTTPServer

The command python -m simplehttpserver starts a simple HTTP server in Python 2 that serves files from the current directory.

The capabilities Array

In the request payload, we would want to send a list of feature flags These faeature flags are abbreviated to minimize payload size and tampering. We determine the supported functionalities in the client - The client could be a Mobile App, A web view, or web app running inside a browser. We send these to the backend API - Each type code represents a specific capability that the client can handle or is requesting to use.
