Oleg Kalnichevski commented on HTTPCLIENT-928:
----------------------------------------------
There is absolutely no need to duplicate the functionality of
DefaultRedirectHandler. What is wrong with just extending the class?
---
DefaultHttpClient httpclient = new DefaultHttpClient();
RedirectHandler redirectHandler = new DefaultRedirectHandler() {
public URI getLocationURI(
final HttpResponse response, final HttpContext context) throws
ProtocolException {
URI uri = super.getLocationURI(response, context);
System.out.println("----------------------------------------");
System.out.println("Redirected to: " + uri);
System.out.println("----------------------------------------");
return uri;
}
};
httpclient.setRedirectHandler(redirectHandler);
HttpHost target = new HttpHost("www.google.com", 80, "http");
HttpGet httpget = new HttpGet("/");
HttpResponse response = httpclient.execute(target, httpget);
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
System.out.println("----------------------------------------");
HttpEntity entity = response.getEntity();
if (entity != null) {
entity.consumeContent();
}

> Can't get list of redirect locations
> ------------------------------------
>
> Key: HTTPCLIENT-928
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-928
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpClient
> Affects Versions: 4.0.1
> Reporter: Ryan Stewart
>
> HttpClient does a great job of following redirects, but afterward there
> doesn't seem to be any way to see the URLs that it followed in the redirect
> chain. They are stored internally by the DefaultRedirectHandler in the
> HttpContext in an attribute named "http.protocol.redirect-locations", but the
> RedirectLocations object that contains them stores them in a Set, so there's
> no way of knowing in what order the URLs were visited.
> Here's an example of why I need it:
> 1) Use HttpClient to retrieve http://foo.com
> 2) http://foo.com returns a 301 redirect to http://foo.com/bar, so HttpClient
> follows the redirect and returns the page to me
> 3) http://foo.com/bar refers to a relative resource like "baz.html".
> That relative resource should resolve to "http://foo.com/bar/baz.html";. I
> only know that, though, if I can look at the redirect URL that HttpClient got
> in step 2. Currently, I don't seem to be able to do that.
