13
15 Pass a long indicating the max. The set number will be used as the max‐
16 imum amount of simultaneously open connections that libcurl may keep in
17 its connection cache after completed use. By default libcurl will
18 enlarge the size for each added easy handle to make it fit 4 times the
19 number of added easy handles.
20
21 By setting this option, you can prevent the cache size from growing
22 beyond the limit set by you.
23
24 When the cache is full, curl closes the oldest one in the cache to pre‐
25 vent the number of open connections from increasing.
26
27 This option is for the multi handle's use only, when using the easy
28 interface you should instead use the CURLOPT_MAXCONNECTS(3) option.
29
30 See CURLMOPT_MAX_TOTAL_CONNECTIONS(3) for limiting the number of active
31 connections.
