In addition to the usual HTTP authentication methods, HTTPS proxies also support client certificates. Similarly, since CONNECT requests are sent over a protected channel, the hostnames for proxied URLs is also not revealed. Example identifier (URI): This works like an HTTP proxy, except the communication to the proxy server is protected by TLS, and may negotiate HTTP/2 (but not QUIC).īecause the connection to the proxy server is secure, requests sent through the proxy are not sent in the clear as with an HTTP proxy. ![]() Example identifier (PAC): HTTPS proxy:8080.HTTP proxies in Chrome support the same HTTP authentiation schemes as for target servers: Basic, Digest, Negotiate, NTLM. However when establishing the tunnel, the hostname of the target URL is sent to the proxy server in the clear. When proxying requests through an HTTP proxy, the TLS exchange is forwarded through the proxy using the CONNECT method, so end-to-end encryption is not broken. ![]() HTTP proxies can proxy ws:// and wss:// URLs.Ĭommunication to HTTP proxy servers is insecure, meaning proxied requests are sent in the clear. When using an HTTP proxy in Chrome, name resolution is always deferred to the proxy. Generally when one refers to a “proxy server” or “web proxy”, they are talking about an HTTP proxy.
