Description

We have seen many issues related to Checkpoint upload.
Currently upload happens with 2 GET requests.
One limitation here is, both checkpointer and the target should have the http server running.

So, to improve further, uploading checkpoint via POST/PUT HTTP request will make the upload clear and one way communication.
