Summary
Successfully using libcurl to do a transfer to a specific HTTP origin (`hostA`) with **Digest**...
Details

Successfully using libcurl to do a transfer to a specific HTTP origin (hostA) with Digest authentication and then changing the origin to a different one (hostB) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the Authorization: header field meant for hostA, to hostB.
