CURLMOPT_PIPELINING – enable/disable HTTP pipelining Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING, bool onoff); DescriptionSet the onoff parameter to 1 to make libcurl use HTTP pipelining for HTTP 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…
CURLMOPT_MAX_TOTAL_CONNECTIONS – max simultaneously open connections Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_TOTAL_CONNECTIONS, long amount); DescriptionPass a long for the amount. The set number will be used as the maximum number of simultaneously open connections in total using this multi handle. For each new session, libcurl will open a new connection up to the limit set…
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); DescriptionPass a long. The set max number will be used as the maximum amount of outstanding requests in a pipelined connection. Only used if pipelining is enabled. When this limit is reached, libcurl will use another connection to…
CURLMOPT_MAX_HOST_CONNECTIONS – set max number of connections to a single host Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_HOST_CONNECTIONS, long max); DescriptionPass a long to indicate max. The set number will be used as the maximum amount of simultaneously open connections to a single host. For each new session to a host, libcurl will open a new…
CURLMOPT_MAXCONNECTS – set size of connection cache Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max); DescriptionPass a long indicating the max. The set number will be used as the maximum amount of simultaneously open connections that libcurl may keep in its connection cache after completed use. By default libcurl will enlarge the size for each…
CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE – size threshold for pipelining penalty Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, long size); DescriptionPass a long with a size in bytes. If a pipelined connection is currently processing a request with a Content-Length larger than this CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE(3), that pipeline will then not be considered for additional requests, even if it is shorter than…
CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE – chunk length threshold for pipelining Synopsis#include <curl/curl.h> CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE, long size); DescriptionPass a long with a size in bytes. If a pipelined connection is currently processing a chunked (Transfer-encoding: chunked) request with a current chunk length larger than CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE(3), that pipeline will not be considered for additional requests, even if it…
