In Java you can use URL.openConnection() to get a HttpURLConnection (you'll need to cast). On this you can call setInstanceFollowRedirects(false).

Then you can use getResponseCode() and see if HTTP_MOVED_PERM (301), HTTP_MOVED_TEMP (302) or HTTP_SEE_OTHER (303). They all indicate redirection.

If you need to know where you're being redirected to, then you can use getHeaderField("Location") to get the location header.
