For example, >>> >>> * HTTP proxy: curl -x http://172.17.0.2:3128/ ... >>> https://example.com >>> * HTTPS proxy: curl -x https://172.17.0.2:3129/ ... >>> https://example.com >> Yes indeed, requesting with curl works unless the web browsers > As far as I can tell based on the information you have provided, your browser is not doing what you want it to do.
