Answer 1

Create a new class that does inherit MonoBehaviour, then call that.

Example of Javascript(unity) way
// Get the latest webcam shot from outside “Friday’s” in Times Square
var url = “http://images.earthcam.com/ec_metros/ourcams/fridays.jpg”;
function Start () {
// Start a download of the given URL
var www : WWW = new WWW (url);

    // Wait for download to complete
    yield www;

    // assign texture
    renderer.material.mainTexture = www.texture;
}

[EDIT] Example of C# way

/// Gets the response.
/// 
/// <param name="StrURL">The URL.
/// HTML source
public string GetResponse(string StrURL)
{
    string strReturn = "";
    HttpWebRequest objRequest = null;
    IAsyncResult ar = null;
    HttpWebResponse objResponse = null;
    StreamReader objs = null;
    try
    {

        objRequest = (HttpWebRequest)WebRequest.Create(StrURL);
        ar = objRequest.BeginGetResponse(new AsyncCallback(GetScrapingResponse),     objRequest);

        //// Wait for request to complete
        ar.AsyncWaitHandle.WaitOne(1000 * 60, true);
        if (objRequest.HaveResponse == false)
        {
            throw new Exception("No Response!!!");
        }

        objResponse = (HttpWebResponse)objRequest.EndGetResponse(ar);
        objs = new StreamReader(objResponse.GetResponseStream());
        strReturn = objs.ReadToEnd();
    }
    catch (Exception exp)
    {
        throw exp;
    }
    finally
    {
        if (objResponse != null)
        objResponse.Close();
        objRequest = null;
        ar = null;
        objResponse = null;
        objs = null;
    }
    return strReturn;
}

/// Gets the scraping response.
///
/// <param name="result">The result.
protected void GetScrapingResponse(IAsyncResult result)
{
    //here you will need to cast/parse the response into what ever type you require e.g. a texture, an xml file, an asset bundle, ect.
}

Call like so

GetResponse('http://images.earthcam.com/ec_metros/ourcams/fridays.jpg');   

[Edit]

Basicly Javascript files in Unity automatically inherit from MonoBehavior.

If you are absolutly certain you cant/wont just create a class that inherits monobehaviour (Example #1) to do the work for you, then your asking how to do a normal XMLHttpRequest to a url.

Javascript Example here:

var xmlHttp = null;

function GetServerInfo()
{
    var Url = "http://localhost";

    xmlHttp = new XMLHttpRequest(); 
    xmlHttp.onreadystatechange = ProcessRequest;
    xmlHttp.open( "GET", Url, true );
    xmlHttp.send( null );
}

function ProcessRequest() 
{
    if ( xmlHttp.readyState == 4 && xmlHttp.status == 200 ) 
    {
        if ( xmlHttp.responseText == "Not found" ) 
        {

        }
        else
        {
            var info = eval ( "(" + xmlHttp.responseText + ")" );
            //Here is where it will get super tricky. You will need to parse these objects into unity objects.
        }                    
    }
}

The really complicated part of this is you will need to parse your http response into unity objects…
