VMOD_PROXY(3) Library Functions Manual VMOD_PROXY(3) NAME vmod_proxy - Vinyl Cache Module to extract TLV attributes from PROXYv2 SYNOPSIS import proxy [as name] [from "path"] STRING alpn() STRING authority() BOOL is_ssl() BOOL client_has_cert_sess() BOOL client_has_cert_conn() INT ssl_verify_result() STRING ssl_version() STRING client_cert_cn() STRING ssl_cipher() STRING cert_sign() STRING cert_key() DESCRIPTION vmod_proxy contains functions to extract proxy-protocol-v2 TLV attributes as described in <https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt> . STRING alpn() Extract ALPN attribute. Example: set req.http.alpn = proxy.alpn(); Restricted to: client. STRING authority() Extract authority attribute. This corresponds to SNI from a TLS connection. Example: set req.http.authority = proxy.authority(); Restricted to: client. BOOL is_ssl() Report if proxy-protocol-v2 has SSL TLV. Example: if (proxy.is_ssl()) { set req.http.ssl-version = proxy.ssl_version(); } Restricted to: client. BOOL client_has_cert_sess() Report if the client provided a certificate at least once over the TLS ses- sion this connection belongs to. Restricted to: client. BOOL client_has_cert_conn() Report if the client provided a certificate over the current connection. Restricted to: client. INT ssl_verify_result() Report the SSL_get_verify_result from a TLS session. It only matters if client_has_cert_sess() is true. Per default, value is set to 0 (X509_V_OK). Example: if (proxy.client_has_cert_sess() && proxy.ssl_verify_result() == 0) { set req.http.ssl-verify = "ok"; } Restricted to: client. STRING ssl_version() Extract SSL version attribute. Example: set req.http.ssl-version = proxy.ssl_version(); Restricted to: client. STRING client_cert_cn() Extract the common name attribute of the client certificate's. Example:: set req.http.cert-cn = proxy.client_cert_cn(); Restricted to: client. STRING ssl_cipher() Extract the SSL cipher attribute. Example: set req.http.ssl-cipher = proxy.ssl_cipher(); Restricted to: client. STRING cert_sign() Extract the certificate signature algorithm attribute. Example: set req.http.cert-sign = proxy.cert_sign(); Restricted to: client. STRING cert_key() Extract the certificate key algorithm attribute. Example: set req.http.cert-key = proxy.cert_key(); Restricted to: client. SEE ALSO * vinyld(1) * vsl(7) COPYRIGHT Copyright (c) 2018 GANDI SAS All rights reserved.
