Rather than closing a socket connection after an HTTP request, it will add it to an idle connection pool, and if you try to make another HTTP request before the idle connection timeout (90 seconds by default), then it will re-use that existing connection rather than creating a new one. So we need to get the URL of the test server and use it instead of the actual service URL. By default, the Golang HTTP client will do connection pooling. When starting, the server chooses any available open port and uses that. Using HTTP request, we can request resources such as.

The following piece of code will demonstrate this point.

However 11.22.33.44 and are considered two different hosts even though both serve the exact same content. Golang Time Now With Code Examples - GoLang In this session, we will try our hand at solving the Golang Time Now puzzle by using the computer language - GoLang. Then is considered the same host even though it is served by two different IP addresses ( 10.20.30.40 and 11.22.33.44 - note: DNS load balancers do not handle HTTP request instead it handles DNS requests and will send different IP addresses to different clients to load-balance) If you have two servers configured like the following: ┌───── HTTP Server 1 (10.20.30.40) Note that it does not depend on the server answering the request.
