If you enable location following, curl will automatically load any redirected
pages. In both cases you will receive the data for the final page loaded,
whether redirected or not. If you are not interested in the contents of
the redirected page, you can disable location following and just look at
the returned HTTP error code. A code in the 3xx range means you were
redirected, and a code in the 2xx range means no redirection.

If you are asking how to do this with libcurl, you should be asking it
on the curl-library mailing list instead.
