ne_session_create, ne_close_connection, ne_session_destroy — set up HTTP sessions
|const char *scheme,|

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 the
ne_session_create function; the
parameters specify the origin server to use, along with
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
To enable SSL/TLS for the session, pass the string
"https" as the
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).
To use a proxy server for the session, it must be configured (see ne_session_proxy) before any requests are created from session object.
Further per-session options may be changed using the ne_set_session_flag interface.
If it is known that the session will not be used for a
significant period of time,
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 session object must not be destroyed until
after all associated request objects have been
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
error code); see ne_request_dispatch for
Create and destroy a session:
ne_session *sess; sess = ne_session_create("http", "host.example.com", 80); /* ... use sess ... */ ne_session_destroy(sess);
