HttpURLConnection timeout settings

Question

I want to return false if the URL takes more then 5 seconds to connect - how is this possible using Java? Here is the code I am using to check if the URL is valid

HttpURLConnection.setFollowRedirects(false);
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
con.setRequestMethod("HEAD");
return (con.getResponseCode() == HttpURLConnection.HTTP_OK);

Answer 1

HttpURLConnection has a setConnectTimeout method.

Just set the timeout to 5000 milliseconds, and then catch java.net.SocketTimeoutException

Your code should look something like this:

try {
   HttpURLConnection.setFollowRedirects(false);
   HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
   con.setRequestMethod("HEAD");

   con.setConnectTimeout(5000); //set timeout to 5 seconds

   return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (java.net.SocketTimeoutException e) {
   return false;
} catch (java.io.IOException e) {
   return false;
}
