detecting redirects with GetMethod
1. If I follow redirects
HttpClient client = new HttpClient();
GetMethod method = new GetMethod("http://....";
method.setFollowRedirects(true);
client.executeMethod(method);
System.out.println(method.getURI());
method.releaseConnection();
Yes, then I can compare the first and the second URLs.
2. If I do not follow the redirect
HttpClient client = new HttpClient();
GetMethod method = new GetMethod("http://....";
method.setFollowRedirects(false);
client.executeMethod(method);
Header header = method.getResponseHeader("Location");
// when header!=null
System.out.println(header.getValue());
method.releaseConnection();
Which solution do you think is nicer or less resource intensive? I need
to do about 17,000 validations so I care about speed too.
Thanks.

The above code samples are not equivalent, as the second one does not
fetch the redirected URL.

Then I suggest you try some tests to measure speed and resource usage.
