Post #375

#Mac#Beta Version 5.4.0-2461 * The HTTP capture function has been significantly improved, with the addition of automatic shutdown and MITM automatic activation features. At the same time, related settings are no longer written into the main configuration. * New proxy protocol supported: Hysteria2. Please visit the project page for more information. https://github.com/apernet/hysteria. Proxy declaration example: Proxy = hysteria2, 1.2.3.4, 443, password=pwd, download-bandwidth=100. * Completed support for ECN (Explicit Congestion Notification) of Vector (Surge Ponte) and TUIC protocols, significantly improving bandwidth performance in poor network environments. * Due to compatibility issues, this function is turned off by default. Please enable it by configuring the ecn=true parameter for a TUIC policy. * Added automatic recognition of HTTP/HTTPS protocols 1. Requests sent to ports 80/443 will wait for the client to send the first data packet and then determine whether it is a valid HTTP/HTTPS request to decide how to handle it. If it is not a valid HTTP request, or if the first packet is not received within 300ms, it will fall back to TCP forwarding mode. Therefore, for requests using port 80, there is no longer a need to configure the force-http-engine-hosts parameter. 2. Automatically recognizes the TLS Client Hello message and extracts SNI, adding rules for SNI and MITM hostname matching. 3. Protocol auto-recognition is only enabled for ports 80/443 because some protocols are initiated by the server sending data first, such as SSH, IMAP, FTP. Waiting for client data before proceeding will cause unnecessary delays for these requests. HTTP requests on other ports that need to be handled by the HTTP engine still need to be configured with force-http-engine-hosts. 4. MITM still requires hostname configuration to be activated, but the tcp-connection parameter is no longer needed and will be effective for TCP requests by default. 5. Added the parameter always-raw-tcp-hosts, which forcibly shuts down active protocol detection for specific hostnames. It is written in the same way as the force-http-engine-hosts parameter. * The DOMAIN, DOMAIN-SUFFIX, DOMAIN-KEYWORD rules have added an optional parameter extended-matching. When this parameter is set, the rule will also try to match both the SNI and the HTTP Host Header (or :authority). * Tips: If you want it to be effective only for SNI, you can use the AND logic rule combined with the PROTOCOL,HTTPS rule. * Since forwarding QUIC traffic through TCP-based proxies can lead to performance issues and traffic waste, all proxy policies have added a block-quic parameter, which can be set to auto (default), on, or off. When enabled, if QUIC traffic is encountered while using this policy, it will automatically use REJECT-NO-DROP to revert to HTTPS/TCP connections. * For the TUIC/WireGuard/Vector(Ponte) protocols, QUIC traffic will be allowed under auto, while it will not be allowed for other proxy protocols under auto. * For QUIC traffic that hits the MITM hostname, it will also be automatically rejected. * Improved compatibility of the HTTP engine and fixed compatibility issues with some non-standard self-implemented HTTP clients. * Other improvements.
