When I do post request

POST(url,path="/api/compute",accept("text/plain"),content_type("application/json"),body=jsonRequest)

and the server reply with HTTP 302 redirect, the httr (or curl?) follows the new location but issues GET request to this new location instead of origin all POST.

The traffic capture:

Request 1:

User-Agent: libcurl/7.47.1 r-curl/0.9.7 httr/1.1.0
