In the case of a redirect the server sets the response header 'location' to the value of the new page URI. This can be either a relative or absolute URI. You can process it using something like:
String url1 = "http://...";; PostMethod httpPostMethod = new PostMethod(url1); httpPostMethod.addParameter("...", "..."); httpClient.executeMethod(httpPostMethod);
if (**methodWasRedirected**) {
URI redirectLocation = new URI(
httpPostMethod.getURI(),
httpPostMethod.getResponseHeader("location").getValue()
);
httpPostMethod = new PostMethod(redirectLocation);
httpPostMethod.addParameter("...", "...");
httpClient.executeMethod(httpPostMethod);

hi mike,
i understand you perfectly and what you said makes sense. the problem is that, without followRedirects set to true, the URL I got from httpPostMethod.getURI().toString() (httpPostMethod is an instance of PostMethod) is the same as the one I pass to the PostMethod constructor while creating httpPostMethod. In other words:
String url1 = "http://...";; PostMethod httpPostMethod = new PostMethod(url1); httpPostMethod.addParameter("...", "..."); httpClient.executeMethod(httpPostMethod); String url2a = httpPostMethod.getURI().toString();
url1 is equal to url2, and I need to obtain the *redirected* url2.
Any tip?

Hi Santos,
There's no way to make PostMethod automatically redirect, other than subclassing and overriding setFollowRedirects().
I question if this is what you want though. Generally a redirect on post indicates that the post succeeded and that the response is to be read from the redirected page. So you would perform a POST to http://somehost/form and be redirected to http://somehost/response. You would then want to do a GET on http://somehost/response.
In either case it is also possible to handle the redirect manually by checking the response code and getting the location header.

Hi all,
I writing to ask you if there's any chance to setFollowRedirects(true) to an instance of PostMethod. I've read in the source that "Entity enclosing requests cannot be redirected without user intervention", but I really need a way to get around this limitation. I know that this is probably due to the HTTP POST spec itself, but I need to invoke an HTTP POST that performs redirection.
