    Exclamation Problem with CraigList Checker

    Hi
    I am trying to build an application that checks whether there has been a new post in a specific craigslist section "Computers for example"
    so I am using the getLastModified() from the HttpUrlConnection Class (the code is shown below), when I test this code on other websites it works just fine, but with craigslist website it keeps telling me there is an update and when I check I find no update, so any idea about why is it behaving like that?

    Java Code:
    import java.net.HttpURLConnection;
    import java.net.URL;
    import java.util.Date;
    
    public class Main{
      public static void main(String args[]) throws Exception {
        URL url = new URL("http://orlando.craigslist.org/sya/");
        HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
    
        long date = httpCon.getLastModified();
        if (date == 0)
          System.out.println("No last-modified information.");
        else
          System.out.println("Last-Modified: " + new Date(date));
    
     }
    }
    Thank you and Regards.
    Anderson.

    Can't that date be somewhere in the past? (unequal to zero)

    kind regards,

    Thank you for your reply, I should have said my code is included in a while(true) loop which performs the previous command each 5 seconds so it keeps checking.

    Regards.
