.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>
|
|
|
|
CURLMcode curl_multi_setopt(CURLM *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 (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
|
|
\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.
|
|
|
|
This set limit is also used for proxy connections, and then the proxy is
|
|
considered to be the host for which this limit counts.
