How can you determine that a certain request is delayed?

To determine if a specific request is delayed in Go, you can measure the request's execution time using the time package.

Example:

package main

import (
    "fmt"
    "net/http"
    "time"
)

func main() {
    start := time.Now()

    resp, err := http.Get("https://example.com")
    if err != nil {
        fmt.Println("Request error:", err)
        return
    }
    defer resp.Body.Close()

    duration := time.Since(start)
    fmt.Printf("Request execution time: %v\n", duration)

    // If the time exceeds the threshold, consider it delayed
    threshold := 500 * time.Millisecond
    if duration > threshold {
        fmt.Println("The request is delayed")
    } else {
        fmt.Println("The request completed quickly")
    }
}

Thus, by measuring the time from start to end of the request, you can determine whether it exceeds the acceptable threshold and consider the request "delayed".
