Attempt at using HTTPRequest, what are we doing wrong here, Deuce?

exec/wget.js

+/* $Id: */
+
+load("http.js");
+
+var url = argv[0];
+var filename=file_getname(url);
+
+var file = new File(filename);
+
+if(!file.open("w"))
+	print("error " + file.error + " opening " + file.name);
+else {
+	var contents = new HTTPRequest().Get(url);
+	file.write(contents);
+	file.close();
+}
