NE_SET_REQUEST_E(3) neon API reference NE_SET_REQUEST_E(3)NAMEne_set_request_expect100 - function to enable Expect: 100-continue sup‐
port
SYNOPSIS
#include <ne_request.h>
void ne_set_request_expect100 (ne_request *request, int flag);
DESCRIPTION
An extension introduced in the HTTP/1.1 specification was the use of
the Expect: 100-continue header. This header allows an HTTP client to
be informed of the expected response status before the request message
body is sent: a useful optimisation for situations where a large mes‐
sage body is to be sent. The ne_set_request_expect100 function can be
used to enable this feature by passing the flag parameter as any
non-zero integer.
Warning
Unfortunately, if this header is sent to a server which is not
fully compliant with the HTTP/1.1 specification, a deadlock oc‐
curs resulting in a temporarily "hung" connection. neon will re‐
cover gracefully from this situation, but only after a 15 second
timeout. It is highly recommended that this option is not en‐
abled unless it is known that the server in use correctly imple‐
ments Expect: 100-continue support.
