The problem is that I can not simply correct that URL and

condition sometimes provided by user . The client side can not judge "
http://localhost:8080/foo"; is a request for "foo" resource in root
context or a request url for the default page in foo context. Server side
has that information and can judge it . If there is a foo context , it will
reply the redirect response.
httpunit can help that. Actually I want to know if there is second
option(configure tomcat to support that )
Tomcat behaves correctly. Your clients send incorrect URLs.
You really should not hack Tomcat to handle redirects in a different way.
Since you use HttpClient (I mean
org.apache.commons.httpclient.HttpClient) you can check response status
code and perform second request if status code is one of
HttpStatus.SC_MOVED_TEMPORARILY or HttpStatus.SC_MOVED_PERMANENTLY. E.g.:
client.executeMethod(method);
responseCode = method.getStatusCode();
responseBody = method.getResponseBodyAsString();
if (responseCode == HttpStatus.SC_MOVED_TEMPORARILY || responseCode ==
HttpStatus.SC_MOVED_PERMANENTLY) {
String redirectLocation;
Header locationHeader = method.getResponseHeader("Location");
if (locationHeader != null) {
redirectLocation = locationHeader.getValue();
method = new GetMethod(redirectLocation);
client.executeMethod(method);
responseCode = method.getStatusCode();
responseBody = method.getResponseBodyAsString();
}
}
I really do not understand your problem ;-)
If you don't have absolutely any control on URLs clients generate or
http-client code your application uses you can try following:
Implement simle servlet that will accept any URL as parameter. Servlet
will use http-client in way described before (e.g. will handle redirects).
Tell your clients to generate URLs like:
http://host/your_servlet?url=url_to_fetch
In other words you should implemet proxy that will handle redirects itself.
Finally, your clients will not see any 302 redirects.
