I think they added a bit of polish&#x2F;magic compared to what you&#x27;d get in a plain https proxy that you could setup yourself, since when visiting an HTTPS page it&#x27;ll show the certificate information from the site that you&#x27;re visiting, and not the one from the actual machine you&#x27;re connecting to (the proxy).<p>Similarly (unlike poorly setup proxies like Lenovo&#x27;s Superfish) it also prevents connection to sites with invalid certificates.<p>(I wrote the same comment in the gist)
