What is an HTTPS Proxy?

An HTTPS proxy handles encrypted web traffic by supporting the CONNECT method, which establishes a secure tunnel between the client and the target server through the proxy. The proxy facilitates the encrypted connection without being able to inspect the encrypted payload, maintaining end-to-end encryption.

The CONNECT Tunnel for Encrypted Traffic

When a client needs to access an HTTPS site through a proxy, it sends a CONNECT request to the proxy with the target hostname and port. The proxy establishes a TCP connection to the target server and then relays raw bytes between the client and server, creating a transparent tunnel. The TLS handshake occurs directly between the client and the target server through this tunnel, meaning the proxy cannot read the encrypted traffic. The proxy only knows the destination hostname and port, not the content.

Sending a CONNECT request to gate.hexproxies.com:8080 for target example.com:443 creates this tunnel. The proxy sees you are connecting to example.com but cannot inspect the encrypted payload flowing through.

HTTPS Support as a Baseline Requirement

HTTPS proxies are essential in today's web where over 95% of traffic is encrypted. Any modern proxy solution must support HTTPS to be useful for real-world applications. Hex Proxies fully supports HTTPS across all proxy products, ensuring your encrypted traffic passes seamlessly while maintaining both security and proxy anonymity.
