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 parameters. 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.
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);
