Get is getting data from web server. and new WWW("https://urlexample.com");
with a url but without a second parameter is doing a Get.
i.e.
using UnityEngine;
using System.Collections;
public class ExampleClass : MonoBehaviour
{
public string url = "http://google.com";
IEnumerator Start()
{
WWW www = new WWW(url); // One get.
yield return www;
Debug.Log(www.text); // The data of the url.
}
}
