HTTP multipart-mixed POST (for a UPS Package Level Detail PLD Request)

See more HTTP Examples

Demonstrates how to create a POST for a UPS Package Level Detail PLD Request. The request must be a multipart-mixed request having two sub-parts. The first is a application/x-www-form-urlencoded with name=value URL encoded pairs. The second is a application/x-ups-binary containing a UPS PLD request.

The HTTP request created by this example looks like this:

POST /hapld/tos/kdwhapltos HTTP/1.1

--    method is called.
