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.
