I did this

I send a POST request which has an auto generated unique token and confirmation of receipt code which i auto incremental

I expected the following

Each request with it unique token should only have one unique receipt confirmation code. However each unique request had two different confirmation codes which are incrementally sequential which means curl is posting the same request twice when evoked once.

curl/libcurl version

7.45.0

[curl -V output]

operating system

x86_64-redhat-linux-gnu
