How to Ensure HTTPS Client Connection Reuse in Go?

Go HTTPS Client Connection Reuse

In Go, the default behavior of the HTTPS client is to reuse connections. However, if you encounter an issue where new connections are established without reusing the existing ones, it could be due to the fact that the response is not closed properly.

When using the HTTPS client, closing the response is crucial for connection reuse. To close the response, use resp.Close(). Additionally, it's recommended to read the response body until completion before closing it, using io.Copy(ioutil.Discard, resp.Body) for example.

Solution:

To ensure connection reuse, perform the following steps:

1. Read the HTTP response until the body is complete.
2. Call resp.Body.Close() to release the connection.

By adhering to these steps, you can ensure that the HTTPS client operates correctly and that connections are reused as intended.
