Redirect problems in HTTP client of Jakarta Commons
Hi,
I am using the HTTPClient() to get the content of a site
"http://www.expedia.com", but I got the following exception saying
redirecting to a different host is not implemented. But when I use the URL
class in jdk, i am able to get the content of the site. Is it collect to say
HTTP client is build on top of the URL class in JDK, if yes, if I can access
site using the URL class, why I can't access site using HttpClient? Or Did I
do something in my problem below?
Thanks for any suggestion.
My program:
public static void main(String[] args) throws Exception {
HttpClient hc = new HttpClient();
UrlGetMethod ugm = new
UrlGetMethod("http://www.expedia.com");
hc.startSession(new URL("http://www.expedia.com"));
hc.executeMethod(ugm);
}
The log file:
2002-04-27 21:50:16,296 [main] INFO httpclient.wire - <<
"<head><title>Object moved</title></head>
<body><h1>Object Moved</h1>This object may be found <a
HREF="http://expedia.msn.com/Default.asp?FromServerName=www.expedia.com">her
e</a>.</body>

org.apache.commons.httpclient.HttpMethod - Server is attempting to redirect
a different host, which is currently not supported. Returning 302.

Hi,
HttpClient currently doesn't support cross-host redirections (for security reasons ?).
You will have to implement the redirection mechanism yourself at the application level.
Such an implementation is available in the JDAVMail project
