/*
|
|
* This code sets up multiple easy handles that transfer a single file from
|
|
* the same URL, in a serial manner after each other. Due to the connection
|
|
* sharing within the multi handle all transfers are performed on the same
|
|
* persistent connection.
|
|
*
|
|
* This source code is used for lib526, lib527 and lib532 with only #ifdefs
|
|
* controlling the small differences.
|
|
*
|
|
* - lib526 closes all easy handles after
|
|
* they all have transfered the file over the single connection
|
|
* - lib527 closes each easy handle after each single transfer.
|
|
* - lib532 uses only a single easy handle that is removed, reset and then
|
|
* re-added for each transfer
|
|
*
|
|
* Test case 526, 527 and 532 use FTP, while test 528 uses the lib526 tool but
|
|
* with HTTP.
