32 Pass a long indicating the \fBmax\fP. The set number will be used as the
33 maximum amount of simultaneously open connections that libcurl may keep in its
34 connection cache after completed use. By default libcurl will enlarge the size
35 for each added easy handle to make it fit 4 times the number of added easy

41 When the cache is full, curl closes the oldest one in the cache to prevent the
42 number of open connections from increasing.
44 This option is for the multi handle's use only, when using the easy interface
45 you should instead use the \fICURLOPT_MAXCONNECTS(3)\fP option.
