handle that is part of a multi handle first removes the handle from the stack. - Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL session-ID re-use on demand since there obviously are broken servers out there that misbehave with session-IDs used.

* 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 _and_ lib527 with only #ifdefs
|
|
* controlling the small differences. lib526 closes all easy handles after
|
|
* they all have transfered the file over the single connection, while lib527
|
|
* closes each easy handle after each single transfer. 526 and 527 use FTP,
|
|
* while 528 uses the lib526 tool but use HTTP.
