I try to use the following method to read pages from Internet, but sometime=
s the program will choke at the place of (line =3D reader.readLine()) !=3D =
null), it tries to read content from internet again and again but still fai=
ls to get the line content, then the program stops at this position. How ca=
n I solve this problem, if it is possible to use another method the downloa=
d pages from internet or when the program is choked, if it is possible to s=
top it and restart the program again?




public  String getHTMLResource(String htmlFile) throws IOException {
		StringBuilder Content =3Dnew StringBuilder();
		try {
	String line =3D null;
			URL url =3D new URL(htmlFile);
			URLConnection conn =3D url.openConnection();
            BufferedReader reader =3D new BufferedReader(new InputStreamRea=
der(conn.getInputStream()));
			while ((line =3D reader.readLine()) !=3D null) {
			Content.append(line+"\n");
			}
			reader.close();
		} catch (Exception e) {}
		return Content.toString();
	}
