CURLMOPT_MAX_PIPELINE_LENGTH \- maximum number of requests in a pipeline

.SH SYNOPSIS
|
||
|
|

#include <curl/curl.h>

.SH DESCRIPTION
|
||
|
|
No function since pipelining was removed in 7.62.0.
|
||
|
|
|
||
|
|
Pass a long. The set \fBmax\fP number is used as the maximum amount of
|
||
|
|
outstanding requests in an HTTP/1.1 pipeline. This option is only used for
|
||
|
|
HTTP/1.1 pipelining, not for HTTP/2 multiplexing.
|
||
|
|
|
||
|
|
When this limit is reached, libcurl creates another connection to the same
|
||
|
|
host (see \fICURLMOPT_MAX_HOST_CONNECTIONS(3)\fP), or queue the request until one
|
||
|
|
.nf
|
||
|
|
of the pipelines to the host is ready to accept a request. Thus, the total
