HttpClient unable to 302 this link?

I found a URL that httpclient doesn\'t seem to be handling redirects on: http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/artic

I found a URL that httpclient doesn't seem to be handling redirects on:

http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml

should 302 to: http://www.mtv.com/news/articles/1647243/20100907/story.jhtml

when I look at the headers in the browser everything looks good:

HTTP/1.1 302 Moved Temporarily

Connection: close

However httpclient doesn't seem to give me the final URL. Here is the code I was using

HttpHead httpget = null;
HttpHost target = null;
HttpUriRequest req = null;

String startURL = "http://news.google.com/news/url?sa=t&fd开发者_如何学JAVA=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml";
HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE,HttpClientFetcher.emptyCookieStore);
httpget = new HttpHead(startURL);

HttpResponse response = httpClient.execute(httpget, localContext);

Header[] test = response.getAllHeaders();
for(Header h: test) {
logger.info(h.getName()+ ": "+h.getValue());
}

target = (HttpHost) localContext.getAttribute( ExecutionContext.HTTP_TARGET_HOST );

req = (HttpUriRequest) localContext.getAttribute( ExecutionContext.HTTP_REQUEST );

// STILL PRINTS OUT THE GOOGLE NEWS LINK
finalURL = target+""+req.getURI();

Am I doing something wrong? thanks


Found the answer from the httpclient mailing list...

Google doesn't treat a HEAD and GET the same, so the GET redirects with 302 and the HEAD request gives a 200 OK
