How to Customize HTTP Request Timeouts in Go?

Customizing Timeout for HTTP Requests in Go

Consider a scenario where you're building a URL fetcher in Go, with a list of URLs awaiting retrieval. You're employing http.Get() to request each URL, expecting a response. However, the default timeout for these requests can be excessive, resulting in a slow fetching process. The objective is to establish a custom timeout, approximately 40-45 seconds, after which the fetcher should report "request timed out" and proceed to the subsequent URL.

Embracing the power of Go 1.3, http.Client introduces a Timeout field. By leveraging this field, you can tailor the timeout duration to your specific needs.

Here's a code snippet to illustrate its usage:

client := http.Client{
    Timeout: 5 * time.Second,
}
client.Get(url)

Note that the timeout is specified as a time.Duration value of 5 seconds in this example, which can be adjusted to the desired duration of 40-45 seconds to meet your requirements. By implementing this solution, you'll improve the efficiency of your URL fetcher, ensuring timely responses and smoother operation.
