CURLMOPT_MAX_PIPELINE_LENGTH — maximum number of requests in a pipeline

Synopsis

#include <curl/curl.h>

CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_PIPELINE_LENGTH, long max);

Description

Pass a long. The set max number will be used as the maximum amount of outstanding requests in an HTTP/1.1 pipelined connection. This option is only used for HTTP/1.1 pipelining, not for HTTP/2 multiplexing.

When this limit is reached, libcurl will use another connection to the same host (see CURLMOPT_MAX_HOST_CONNECTIONS(3)), or queue the request until one of the pipelines to the host is ready to accept a request. Thus, the total number of requests in-flight is CURLMOPT_MAX_HOST_CONNECTIONS(3) * CURLMOPT_MAX_PIPELINE_LENGTH(3).

Default

5

Protocols

HTTP(S)

Example
