```csharp
public WWW(string url)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The url to download. Must be '%' escaped.

### Remarks

This function creates and sends a GET request. The stream will automatically start downloading the response.

After the stream is created you have to wait for it to complete, then you can access the downloaded data. As a convenience the stream can be yielded, so you can very easily tell Unity to wait for the download to complete.

***Note:*** URL must be '%' escaped.

### Examples

```csharp
// Get the latest webcam shot from outside "Friday's" in Times Square

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public string url = "https://images.earthcam.com/ec_metros/ourcams/fridays.jpg";
    IEnumerator Start()
    {
        // Start a download of the given URL
        using (WWW www = new WWW(url))
        {
            // Wait for download to complete
            yield return www;

            // assign texture
            Renderer renderer = GetComponent<Renderer>();
            renderer.material.mainTexture = www.textureNonReadable;
        }
    }
}
```
