NAME
ne_set_request_expect100 - function to enable Expect: 100-continue
support
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
message 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 occurs resulting
in a temporarily "hung" connection. neon will recover gracefully from
this situation, but only after a 15 second timeout. It is highly
recommended that this option is not enabled unless it is known that the
server in use correctly implements Expect: 100-continue support.
