ne_session_create

ne_session_create, ne_close_connection, ne_session_proxy, ne_session_destroy - set up HTTP sessions

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.

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.

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.

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

Create and destroy a session:

ne_session *sess;
sess = ne_session_create("http", "host.example.com", 80);
/* ... use sess ... */
ne_session_destroy(sess);
