 This is useful when you want to establish a standard proxy and do some forwarding tasks. But this can also be useless when using as a debug tool.
 
 To work as a debug tool of HTTPS, the proxy itself should do two things : intercept the request and cheat the browser with a valid certificate. This is what you know as the man-in-the-middle attack.
+
 In order to have a browser-trusted certificate, we would sign certificates dynamically. The first thing to do is to generate a self-signed root CA and import to the system keychain. After trusting this CA, all child certs signed by it can be naturally trusted by the browser.

 What this proxy do is to generate and replace a temporary cert for any domain if neccessary. Using it, we can intercept all the https requests for debug. BTW, this is also what the charlse/fiddler do when you check the HTTPS_PROXY in preference settings.
