NE_SESSION_PROXY(3) neon API reference NE_SESSION_PROXY(3) NAME ne_session_proxy, ne_session_socks_proxy, ne_session_system_proxy, ne_set_addrlist - configure proxy servers SYNOPSIS #include <ne_session.h> void ne_session_proxy(ne_session *session, const char *hostname, un- signed int port); void ne_session_system_proxy(ne_session *session, unsigned int flags); void ne_session_socks_proxy(ne_session *session, enum ne_sock_sversion ver- sion, const char *hostname, unsigned int port, const char *username, const char *password); void ne_set_addrlist(ne_session *session, const ne_inet_addr **addrlist, size_t count); DESCRIPTION One (and no more than one) of the functions ne_session_proxy, ne_ses- sion_system_proxy, ne_session_socks_proxy, ne_set_addrlist can be used to configure a proxy server for a given session object. If more than one func- tion is invoked for any given session object, only the last call has ef- fect. If one of the functions is to be used, it must be used before the creation of any request object for the session. HTTP proxy specification The ne_session_proxy function configures use of an HTTP proxy server for the session, the location of which is given by the hostname and port para- meters. If the proxy requires authentication, ne_set_proxy_auth should be used. System proxy configuration The ne_session_system_proxy function configures the session to use any proxy servers specified by the system configuration. Support for this func- tion is platform-specific; if unsupported, the function has no effect. SOCKS proxy configuration The ne_session_socks_proxy function configures the session to use a SOCKS proxy. The version indicates which version of the SOCKS protocol should be used. The hostname and port parameters specify the SOCKS proxy location. Note that a server with only an IPv6 address cannot be used with SOCKS v4 or v4A. The interpretation of the other arguments depends on the version specified: NE_SOCK_SOCKSV4 (version 4) The username parameter must be non-NULL; the password parameter is ig- nored. NE_SOCK_SOCKSV4A (version 4A) The username parameter must be non-NULL; the password parameter is ig- nored. NE_SOCK_SOCKSV5 (version 5) The username parameter may be NULL; if it is non-NULL, the password pa- rameter must also be non-NULL; otherwise, it is ignored.. Origin server address override The ne_set_addrlist function forces use of an address and port the a speci- fied list when establishing a TCP connection, ignoring the "real" hostname and port identifying the origin server for the session (as passed to ne_session_create). The origin server's "real" hostname and port will still be used in the Host header in HTTP requests. When a connection is required, the library will iterate through the addrlist list, attempting to connect to the address addrlist[0] through to addrlist[count-1] in turn, until a connection can be established. RETURN VALUES None of the functions described here has a return value. EXAMPLES Create and destroy a session: ne_session *sess; sess = ne_session_create("http", "host.example.com", 80); ne_session_proxy(sess, "proxy.example.com", 3128); /* ... use sess ... */ ne_session_destroy(sess); SEE ALSO ne_ssl_set_verify, ne_ssl_trust_cert, ne_sock_init, ne_set_session_flag COPYRIGHT Copyright (C) 2001-2024 Joe Orton neon 0.34.0 23 November 2024 NE_SESSION_PROXY(3)
