var g = new Grabber( "Grabber Test MultiRequest", "GBR" );

g.onRun = function( lp )
{

var dt = new Date;

var m = new MultiHTTPRequest( 10 );

var arrRequestHeaders = new Array;
arrRequestHeaders.push( "test: nothing" );

m.addItem( "logo", "GET", "http://www.digiguide.com/i/nav/banner_gradient.gif", "", arrRequestHeaders, "", "" );
m.addItem( "home", "GET", "http://www.digiguide.com/", "", "", "", "" );
m.addItem( "fatbird", "GET", "http://www.fatbird.com/asasdsadsda.asdsa", "", arrRequestHeaders, "", "" );
m.m_grabber = this;

m.onGotFile = function( id, status, statusText, responseBody, responseHeaders )
{
var headers = new HTTPHeaders( responseHeaders );
alert( id + " Length: " + headers.get( "Content-Length" ) + " Status: " + status + " " + statusText );
return true;
}

m.grab();
