What an HTTPS proxy actually is
An HTTPS proxy is a forwarding server that relays your requests to target websites while the connection is wrapped in TLS encryption. When your client asks for an https:// URL, it opens a tunnel to the proxy using the HTTP CONNECT method, the proxy establishes a path to the destination, and your browser or script then performs a normal TLS handshake straight through to that destination.
The important consequence is end-to-end privacy: because the handshake terminates at the target server, not at the proxy, the proxy can see the hostname and port you are reaching but cannot read the encrypted body of your traffic. Passwords, session tokens and form data stay sealed between your machine and the site.
That is the core distinction from an open HTTP proxy, which can inspect and even rewrite unencrypted traffic. With HTTPS proxies from Budget Proxies, the encrypted payload is opaque to every hop in between, which is why HTTPS is the sensible default for almost all real-world work.
