Hello,

We'd like to make sure we don't overwrite an existing object when we upload a file to a server, so we put a header "If-None-Match: *", however, the upload operation always failed with digest authentication. I tracked the code a bit and found out that libcurl was sending two requests, the first request had content-length of 0, the server side responded with creating the object. The second request had the real length, but the operation failed since the request had header "If-None-Match: *", and the object was created by the first request, so the server side responded with http code 413, i.e. precondition failed. Is this the server's issue or libcurl's issue? Thanks.

Lu
