+PERSISTANT CONNECTIONS
+
+  Specifying multiple files on a single command line will make curl transfer
+  all of them, one after the other in the specified order.
+
+  libcurl will attempt to use persistant connections for the transfers so that
+  the second transfer to the same host can use the same connection that was
+  already initiated and was left open in the previous transfer. This greatly
+  decreases connection time for all but the first transfer and it makes a far
+  better use of the network.
+
+  Note that curl cannot use persistant connections for transfers that are used
+  in subsequence curl invokes. Try to stuff as many URLs as possible on the
+  same command line if they are using the same host, as that'll make the
+  transfers faster.
+
+  Persistant connections were introduced in curl 7.7.
