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, unsigned 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 version, 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_session_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 function is invoked for any given session object, only the last call has effect. 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 paramters. 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 function 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 ignored. NE_SOCK_SOCKSV4A (version 4A) The username parameter must be non-NULL; the password parameter is ignored. NE_SOCK_SOCKSV5 (version 5) The username parameter may be NULL; if it is non-NULL, the password parameter 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 specified 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_SESSION_CREATE(3)						neon API reference					      NE_SESSION_CREATE(3)

NAME
ne_session_create, ne_close_connection, ne_session_proxy, ne_session_destroy - set up HTTP sessions SYNOPSIS
#include <ne_session.h> ne_session *ne_session_create(const char *scheme, const char *hostname, unsigned int port); void ne_session_proxy(ne_session *session, const char *hostname, unsigned int port); void ne_close_connection(ne_session *session); void ne_session_destroy(ne_session *session); DESCRIPTION
An ne_session object represents an HTTP session - a logical grouping of a sequence of HTTP requests made to a certain server. Any requests made using the session can use a persistent connection, share cached authentication credentials and any other common attributes. A new HTTP session is created using ne_session_create, giving the hostname and port of the server to use, along with the scheme used to contact the server (usually "http"). Before the first use of ne_session_create in a process, ne_sock_init must have been called to perform any global initialization needed by any libraries used by neon. To enable SSL/TLS for the session, pass the string "https" as the scheme parameter, and either register a certificate verification function (see ne_ssl_set_verify) or trust the appropriate certificate (see ne_ssl_trust_cert, ne_ssl_trust_default_ca). If an HTTP proxy server should be used for the session, ne_session_proxy must be called giving the hostname and port on which to contact the proxy. Further per-session options may be changed using the ne_set_request_flag interface. If it is known that the session will not be used for a significant period of time, ne_close_connection can be called to close the connection, if one remains open. Use of this function is entirely optional, but it must not be called if there is a request active using the session. Once a session has been completed, ne_session_destroy must be called to destroy the resources associated with the session. Any subsequent use of the session pointer produces undefined behaviour. NOTES
The hostname passed to ne_session_create is resolved when the first request using the session is dispatched; a DNS resolution failure can only be detected at that time (using the NE_LOOKUP error code); see ne_request_dispatch for details. RETURN VALUES
ne_session_create will return a pointer to a new session object (and never NULL). EXAMPLES
Create and destroy a session: ne_session *sess; sess = ne_session_create("http", "host.example.com", 80); /* ... use sess ... */ ne_session_destroy(sess); SEE ALSO
