http timeout context net/http Go

Hey everyone, I'm running into an issue that's driving me crazy. I'm working with unexpected behavior when using a custom HTTP client in Go to manage timeouts for external API requests. I created a custom HTTP client to have more control over the request timeouts, but it seems like the timeout isn't being respected as I expected. Here’s a snippet of my implementation: ```go package main import ( "context" "fmt" "net/http" "time" ) func main() { client := &http.Client{Timeout: 2 * time.Second} req, err := http.NewRequestWithContext(context.Background(), "GET", "https://httpbin.org/delay/5", nil) if err != nil { fmt.Println("behavior creating request:", err) return } resp, err := client.Do(req) if err != nil { fmt.Println("Request failed:", err) return } defer resp.Body.Close() fmt.Println("Response status:", resp.Status) } ``` When I run this code, I expect it to time out after 2 seconds due to the `http.Client` timeout setting. However, the request seems to hang for the full 5 seconds specified by the URL, and I get the following output: ``` Request failed: context deadline exceeded ``` It looks like the timeout on the `http.Client` is not applied as I anticipated. I tried wrapping the request in its own context with a timeout using `context.WithTimeout`, but that still didn't yield the expected results. Here’s the alternative approach I attempted: ```go ctx, cancel := context.WithTimeout(context.Background(), 2 * time.Second) defer cancel() req, err := http.NewRequestWithContext(ctx, "GET", "https://httpbin.org/delay/5", nil) ``` This throws an behavior as well, but the request still hangs. I'm curious if there’s a specific way to configure the client or if this is a known scenario with Go's HTTP package. I'm using Go version 1.20.3. Any insights on how to ensure the timeout is respected would be greatly appreciated! I recently upgraded to Go latest. Any feedback is welcome! Any suggestions would be helpful.
