+# NAME
+
+CURLMOPT_MAXCONNECTS - size of connection cache
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAXCONNECTS, long max);
+~~~
+
+# DESCRIPTION
+
+Pass a long indicating the **max**, the maximum amount of connections that
+libcurl may keep alive in its connection cache after use. By default libcurl
+enlarges the size for each added easy handle to make it fit 4 times the number
+of added easy handles.
+
+By setting this option, you prevent the cache size from growing beyond the
+limit set by you.
+
+When the cache is full, curl closes the oldest connection present in the cache
+to prevent the number of connections from increasing.
+
+This option is for the multi handle's use only, when using the easy interface
+you should instead use the CURLOPT_MAXCONNECTS(3) option.
+
+See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
+connections.
+
+Changing this value when there are transfers in progress is possible, and the
+new value is then used the next time checks are performed. Lowering the value
+does not close down any active transfers, it simply does not allow new ones to
+get made.
+
+# DEFAULT
+
+See DESCRIPTION
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURLM *m = curl_multi_init();
+  /* only keep 10 connections in the cache */
+  curl_multi_setopt(m, CURLMOPT_MAXCONNECTS, 10L);
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_multi_setopt(3) returns a CURLMcode indicating success or error.
+
+CURLM_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
