Go (Golang) httptrace Tutorial

Go (Golang) httptrace Tutorial In this episode we are going to explore the httptrace package, a new addition to the Go standard library present from Go1.7. The httptrace package is extremely useful when doing performance analysis and tracing of your http requests when using the Go http client.

Some of these events are for example, DNS resolution, TCP connection creation, Bytes written to the TCP connection, Bytes received from the server, and many more. In this example we are also going to explore HTTP Persistent connections and how to make your Go client re-use an existing tcp connection when doing multiple HTTP requests to the same host.
