CURLMOPT_PIPELINING(3) curl_multi_setopt options CURLMOPT_PIPELINING(3)NAMECURLMOPT_PIPELINING - enable/disable HTTP pipelining
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING, long
bits);
DESCRIPTION
Set the bits parameter to 1 to make libcurl use HTTP pipelining for
HTTP/1.1 transfers done using this multi handle, as far as possible.
This means that if you add a second request that can use an already
existing connection, the second request will be "piped" on the same
connection rather than being executed in parallel.
When using pipelining, there are also several other related options
that are interesting to tweak and adjust to alter how libcurl spreads
out requests on different connections or not etc.
Starting in 7.43.0, the bits parameter's bit 1 also has a meaning and
libcurl is now offering symbol names for the bits:
CURLPIPE_NOTHING
Default, which means doing no attempts at pipelining or multiplexing.
CURLPIPE_HTTP1
If this bit is set, libcurl will try to pipeline HTTP/1.1 requests on
connections that are already established and in use to hosts.
CURLPIPE_MULTIPLEX
If this bit is set, libcurl will try to multiplex the new transfer
over an existing connection if possible. This requires HTTP/2.
DEFAULT
0 (off)
