ne_set_useragent, ne_set_read_timeout, ne_set_connect_timeout, ne_get_scheme, ne_get_server_hostport - common properties for HTTP sessions
#include <ne_session.h>
void ne_set_useragent(ne_session *session, const char *product);
void ne_set_read_timeout(ne_session *session, int timeout);
void ne_set_connect_timeout(ne_session *session, int timeout);
const char *ne_get_scheme(ne_sesssion *session);
const char *ne_get_server_hostport(ne_sesssion *session);
The User-Agent request header is used to identify the software which generated the request for statistical or debugging purposes. neon does not send a User-Agent header unless a call is made to the ne_set_useragent. ne_set_useragent must be passed a product string conforming to RFC2616's product token grammar; of the form "Product/Version".
When neon reads from a socket, by default the read operation will time out after 60 seconds, and the request will fail giving an NE_TIMEOUT error. To configure this timeout interval, call ne_set_read_timeout giving the desired number of seconds as the timeout parameter.
When a connection is being established to a server, normally only the system's TCP timeout handling will apply. To configure a specific (and probably shorter) timeout, the ne_set_connect_timeout can be used, giving the desired number of seconds as the timeout parameter. If 0 is passed, then the default behaviour of using the system TCP timeout will be used.
The scheme used to initially create the session will be returned by ne_get_scheme.
The hostport pair with which the session is associated will be returned by the ne_get_server_hostport; for example www.example.com:8080. Note that the :port will be omitted if the default port for the scheme is used.
Set a user-agent string:
ne_session *sess = ne_session_create(...); ne_set_useragent(sess, "MyApplication/2.1");
Set a 30 second read timeout:
ne_session *sess = ne_session_create(...); ne_set_read_timeout(sess, 30);
ne_session_create, ne_set_session_flag.
