I haven't tried this, but I believe what you'll need to do is check the
HTTP status, and look for a new URL/URI in the response headers. Web
servers usually issue redirect responses with a 300 level response code,
most commonly 301 (permanent redirect) or 302 (temporary redirect). In
either case, they're supposed to provide a new absolute URL, though many
only provide a relative URI (the path and file name on the server) in a
"Location" header. So you'll probably need to issue a new get request to
the new URL. When you're either tired of bouncing around (HTTP clients
are only suggested to handle up to 5 redirects), or when you hit a non
300 level response code, then you're at your final destination, but
there's nothing saying you can't keep the responses from every bounce
along the way...
