  24. /*
  25. * This code sets up multiple easy handles that transfer a single file from
  26. * the same URL, in a serial manner after each other. Due to the connection
  27. * sharing within the multi handle all transfers are performed on the same
  28. * persistent connection.
  29. *
  30. * This source code is used for lib526, lib527 and lib532 with only #ifdefs
  31. * controlling the small differences.
  32. *
  33. * - lib526 closes all easy handles after
  34. * they all have transferred the file over the single connection
  35. * - lib527 closes each easy handle after each single transfer.
  36. * - lib532 uses only a single easy handle that is removed, reset and then
  37. * re-added for each transfer
  38. *
  39. * Test case 526, 527 and 532 use FTP, while test 528 uses the lib526 tool but
  40. * with HTTP.
