Hi, all,

I have an app, which needed to communicating with the web server
(which hold by myself). Sometimes, the server will down.
Now, what I want to know is: How can I get a signal which indicating
the web server is down?

When I using this:
HttpResponse httpResponse = new
DefaultHttpClient().execute(httpRequest);

if the web server is down, it will throw an IOException, I can get a
signal.
However, the responding time of the above method is very long.
Is there any other methods?

Thanks for your help!
