.TH CURLMOPT_MAX_HOST_CONNECTIONS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_multi_setopt options"
.SH NAME
CURLMOPT_MAX_HOST_CONNECTIONS \- set max number of connections to a single host
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_multi_setopt(CURL *handle, CURLMOPT_MAX_HOST_CONNECTIONS, long max);
.SH DESCRIPTION
Pass a long to indicate \fBmax\fP. 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 connection up to the limit set by
\fICURLMOPT_MAX_HOST_CONNECTIONS(3)\fP. When the limit is reached, the
sessions will be pending until a connection becomes available. If
\fICURLMOPT_PIPELINING(3)\fP is enabled, libcurl will try to pipeline if the
host is capable of it.

The default \fBmax\fP value is 0, unlimited.  However, for backwards
compatibility, setting it to 0 when \fICURLMOPT_PIPELINING(3)\fP is 1 will not
be treated as unlimited. Instead it will open only 1 connection and try to
pipeline on it.
