//
// ajax(url[,method][,httpheaders][,cache][,callback])
//
// url: (string): have a guess :-)
// method: (string or false): GET/POST (default GET)
// httpheader: (array or false): headers to be sent e.g. new Array("Connection: Close", "Cookie: firstName=John") - use false if not wanted
// cache: (bool): same guess! - note: seting to false may yield errors due to forged parameter on some websites
// callback: (function or false): ommit if no callback is required, else use function(h,t) { } where h are the headers returned and t is the text returned
//
// notes:
//	if server yield a 302 or 304 header (found, moved, ...) ajax will stop
//	results longer than 32k will go bananas
