This module is not built by default, it should be enabled with the --with-stream_ssl_module configuration parameter. About Proxy Protocol; Proxy Protocol is a protocol developed by HaProxy to solve the problem of easily losing client information during proxying. TLS ensures that no third party may eavesdrop or tampers with any message. When you terminate TLS on HAProxy directly (which is not the worst idea, by the way), you can still forward connection metadata using the proxy protocol, because HAProxy will connect to VerneMQ locally over TCP. A TLS proxy server protects against denial-of-service (DoS) attacks and other security threats. SSLv2. Apr 19, 2021 · Hitch is a libev-based high performance SSL/TLS proxy by Varnish Software.
