Hello Jean-Remi,
1. make the POST request
2. look for the "Location" header
3. make the GET request to the Location
The output you copied shows only the requests you send.
The Location header is not in the request, it is in the
response to step 1. Therefore, I suspect you made a
mistake in step 2, possibly by looking in the wrong place.
You need to do the following:
Header location = postMethod.getResponseHeader("Location");
where 'postMethod' is the method you executed in step 1.
I hope this helps,
Roland

Subject: PostMethod.setFollowRedirects(true); -> do nothing
Sorry to come again with the same question, but I do not know what to
do...
I read carefully your replies and do what you said but...
My problem is that I have to send my first GET request to a specific URL
(I
can not modify that, it is not mine), this page fill a form with my
parameters and submit them automatically to an another URL (in the same
domaine, I know this second URL). The submission is automatic and is in
POST
methode, I have to follow it to catch the resuls...
I catched the cookies.
I tried to make the first request in POST to send my parameters and make
the
second in GET to the forward
URL(http://www.XXX.com/mirror/etape2h.cfm?ref=0144259402). But I have
always
the same error message even if I put the setFollowRedirects method at TRUE
:
>29 janv. 2004 14:53:33 org.apache.commons.httpclient.HttpMethodBase
processRedirectResponse
>INFO: Redirect requested but followRedirects is disabled
I also tried to make the first request under POST for catching the
"location" header, but there is nothing like that in anyone of the
redirection:

Actually the problem is two-fold:
1. "redirect" in HttpClient means: The *same* request ist sent to a
different URL (on the same host). The HTTP Protocol (RFC 2616)
explicitly
forbids this kind of redirection for entity enclosing methods
without any user interaction. That's why the flag is set to false.
2. A Location (redirect) header as a response to a POST request
is handled as a GET request to the new URL by browsers. HttpClients
design
does not currently allow chaning the method on the fly. That's why you
need to handle this yourself.
