NAME

6       ne_session_create, ne_close_connection, ne_session_destroy - set up
7       HTTP sessions
8

SYNOPSIS

10       #include <ne_session.h>
11
12       ne_session *ne_session_create(const char *scheme, const char *hostname,
13                                     unsigned int port);
14
15       void ne_close_connection(ne_session *session);
16
17       void ne_session_destroy(ne_session *session);
18

DESCRIPTION

20       An ne_session object represents an HTTP session - a logical grouping of
21       a sequence of HTTP requests made to a certain server. Any requests made
22       using the session can use a persistent connection, share cached
23       authentication credentials and any other common attributes.
24
25       A new HTTP session is created using the ne_session_create function; the
26       hostname and port parameters specify the origin server to use, along
27       with the scheme (usually "http"). Before the first use of
28       ne_session_create in a process, ne_sock_init must have been called to
29       perform any global initialization needed by any libraries used by neon.
30
31       To enable SSL/TLS for the session, pass the string "https" as the
32       scheme parameter, and either register a certificate verification
33       function (see ne_ssl_set_verify) or trust the appropriate certificate
34       (see ne_ssl_trust_cert, ne_ssl_trust_default_ca).
35
36       To use a proxy server for the session, it must be configured (see
37       ne_session_proxy) before any requests are created from session object.
38
39       Further per-session options may be changed using the
40       ne_set_session_flag interface.
41
42       If it is known that the session will not be used for a significant
43       period of time, ne_close_connection can be called to close the
44       connection, if one remains open. Use of this function is entirely
45       optional, but it must not be called if there is a request active using
46       the session.
47
48       Once a session has been completed, ne_session_destroy must be called to
49       destroy the resources associated with the session. Any subsequent use
50       of the session pointer produces undefined behaviour. The session object
51       must not be destroyed until after all associated request objects have
52       been destroyed.
53

NOTES

55       The hostname passed to ne_session_create is resolved when the first
56       request using the session is dispatched; a DNS resolution failure can
57       only be detected at that time (using the NE_LOOKUP error code); see
58       ne_request_dispatch for details.
59

RETURN VALUES

61       ne_session_create will return a pointer to a new session object (and
62       never NULL).
63

EXAMPLES

65       Create and destroy a session:
66
67           ne_session *sess;
68           sess = ne_session_create("http", "host.example.com", 80);
69           /* ... use sess ... */
70           ne_session_destroy(sess);
