Sets the persistent connection cache size.
The set amount will be the maximum amount of simultaneously open connections that libcurl may cache in this easy handle. Default is 5, and there isn't much point in changing this value unless you are perfectly aware of how this works and changes libcurl's behaviour. This concerns connections using any of the protocols that support persistent connections.

When reaching the maximum limit, curl closes the oldest one in the cache to prevent increasing the number of open connections.

If you already have performed transfers with this curl handle, setting a smaller MaxConnects than before may cause open connections to get closed unnecessarily.
