23 .TH CURLOPT_MAXCONNECTS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
24 .SH NAME
25 CURLOPT_MAXCONNECTS \- maximum connection cache size
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXCONNECTS, long amount);
30 .SH DESCRIPTION
31 Pass a long. The set \fIamount\fP will be the maximum number of simultaneously
32 open persistent connections that libcurl may cache in the pool associated with
33 this handle. The default is 5, and there isn't much point in changing this
34 value unless you are perfectly aware of how this works and changes libcurl's
35 behaviour. This concerns connections using any of the protocols that support
36 persistent connections.
37
38 When reaching the maximum limit, curl closes the oldest one in the cache to
39 prevent increasing the number of open connections.
40
41 If you already have performed transfers with this curl handle, setting a
42 smaller \fICURLOPT_MAXCONNECTS(3)\fP than before may cause open connections to
43 get closed unnecessarily.
44
45 If you add this easy handle to a multi handle, this setting is not
46 acknowledged, and you must instead use \fIcurl_multi_setopt(3)\fP and the
47 \fICURLMOPT_MAXCONNECTS(3)\fP option.
