Oblivious HTTP

Oblivious HTTP (OHTTP) is an IETF network protocol intended to enable anonymous HTTP transactions over the Internet. Its goal is to allow a user to send an HTTP request to a web server without allowing any single entity to see both the content of the request and the sender's IP address, since the IP address could be connected to the identity of the sender. OHTTP is documented in RFC 9458, published in January 2024 by authors affiliated with Mozilla and Cloudflare. The RFC says "Oblivious HTTP is simpler and less costly than more robust systems, like Prio or Tor, which can provide stronger guarantees at higher operational costs."
