Description

This is a simple proxy server to inspect traffic as it goes to httpbin.org

If a request has a JSON payload, and in that payload there's a key value of {"is_malicious": true} then the proxy will intercept the payload and return a 403 error.

If a request repeats, the proxy will log a warning.

The proxy is built on Python and uses the Flask library
