Reference: https://stackoverflow.com/questions/28046100/golang-http-concurrent-requests-post-eof

The app runs multiple goroutine concurrently. If one connection is not completed closed, the connection could be reused. Because go by default use Connection: Keep-Alive.
However, if the server close the connection with Connection: Keep-Alive. the next request receives EOF.
