The proxy server forwards any url_path's or headers passed to it to the httpbin website. It also returns the response code / headers / body from upstream.
To do:
- No concurrency, single process, single thread. We can only handle a single request at once.
- No error handling.
- No limits implemented because of above. I could use
aiohttpor a rate limiting package via a decorator, though. - The output 'wfile' does not conform to HTTP 1.1 standard and thus impossible to open in a browser window (cURL only).
