The standard library's http client as defined in net/http uses a transport
layer connection pool already. I believe it will take care of the scenario
you are trying to solve.

This issue https://github.com/golang/go/issues/23427 has some relevant
discussions and starting points for you to explore more. I also recommend
looking at this post https://blog.golang.org/http-tracing for further
research

 Hi,

 My basic understanding of HTTP protocol is that an HTTP client sent
 request, get response from the HTTP server and then the connection is
 closed.

 My question is how can an HTTP client detect if the underling transport
 connection break. For example if the HTTP server shutdown, is there a way
 to detect that at the client so that the client can start a persistent
 request.

 If possible, how can I do that in golang HTTP client?

Hi,

Yes, that is what intend to implement. Can you help with some information 
about how
I could implement it. 
If possible some libraries or example code.

Are you thinking about implementing a connection pool for your long lived
process?

[go-nuts] How to detect if transport connection break
