David,
Just a few comments
(1) This is unrelated to your problem, but do make sure you release
connection when you are done with the method. In most cases HttpClient
will do its very best to automatically release the connection, but in
some cases (like the response content consumed partially) HttpClient
simply cannot know that the method and the connection associated with it
are not longer needed.
The general pattern should always be
HttpMethod httpmethod = new GetMethod("/whatever");
try {
httpclient.executeMethod(httpmethod);
// do stuff.
} finally {
httpmethod.releaseConnection();
}
This can save you A LOT of grief should you decide to use HttpClient
with a multi-threaded connection manager or if some of your methods do
not consume the response content in its entirety
For details see the tutorial:
http://jakarta.apache.org/commons/httpclient/tutorial.html
(2) As to the main issue, apparently the redirect URL is invalid. I
could possibly say more if I had the log, but the log you attached to
your previous message did not get through. Try attaching the log inline
or send it to me directly
Another idea would be to capture the exact transaction between and the
browser and the site using a traffic analyzer and then implement the
same logic with HttpClient
Hope this helps
Oleg
