Cloudflare Ohttp Gateway
Cloudflare is rolling out a new OHTTP Gateway to help app developers bake privacy into their applications. OHTTP, an IETF standard, enables backends to receive HTTP requests without seeing user IP addresses. The new Cloudflare OHTTP Gateway is a paid add-on that customers can enable through a simple registration process. The gateway works by separating trust between a relay and a gateway, ensuring that no single party sees both client identifiers and request contents.
This separation was introduced in Cloudflare's Privacy Gateway in 2022, which allows users to offer more privacy-preserving experiences. However, customers who have Cloudflare protecting their servers couldn't use the relay before, as it would break OHTTP's privacy model. Now, Cloudflare offers two options: an OHTTP gateway or relay.
OHTTP relays, like the Privacy Gateway, obscure client identifiers, while OHTTP gateways perform cryptographic work to decapsulate and encapsulate requests and responses. Cloudflare's anycast approach enables the OHTTP Gateway to run on every server in its global edge network, minimizing latency. This new service aims to make privacy infrastructure more accessible to developers, building on Cloudflare's existing capabilities for fast, reliable privacy services.
