CURLMOPT_MAX_HOST_CONNECTIOcurl_multi_setopt oCURLMOPT_MAX_HOST_CONNECTIONS(3)NAMECURLMOPT_MAX_HOST_CONNECTIONS - set max number of connections to a sin‐
gle host
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_HOST_CONNEC‐
TIONS, long max);
DESCRIPTION
Pass a long to indicate max. The set number will be used as the maximum
amount of simultaneously open connections to a single host (a host
being the same as a host name + port number pair). For each new session
to a host, libcurl will open a new connection up to the limit set by
CURLMOPT_MAX_HOST_CONNECTIONS(3). When the limit is reached, the ses‐
sions will be pending until a connection becomes available. If CURL‐
MOPT_PIPELINING(3) is enabled, libcurl will try to pipeline if the host
is capable of it.
The default max value is 0, unlimited. However, for backwards compati‐
bility, setting it to 0 when CURLMOPT_PIPELINING(3) is 1 will not be
treated as unlimited. Instead it will open only 1 connection and try to
pipeline on it.
This set limit is also used for proxy connections, and then the proxy
is considered to be the host for which this limit counts.
