How to resend or save a session cookie

Question

I am trying to handle a redirect (302) in Java code, and finally I was able to do this. But I ran into a problem. If a page opens after redirecting, clicking on any link on the page returns me to the login page.

Therefore, I have to write my own redirect implementation:

private HttpMethod loadHttp302Request(HttpMethod method, HttpClient client, int status, String urlString) throws HttpException, IOException { if (status != 302) return null; String[] url = urlString.split("/"); HttpMethod theMethod = new GetMethod(urlString + method.getResponseHeader("Location") .getValue()); theMethod.setRequestHeader("Cookie", method.getResponseHeader("Set-Cookie") .getValue()); theMethod.setRequestHeader("Referrer", url[0] + "//" + url[2]); theMethod.setDoAuthentication(method.getDoAuthentication()); theMethod.setFollowRedirects(method.getFollowRedirects()); int _status = client.executeMethod(theMethod); return theMethod; } 

In my opinion, I cannot resend or save the session cookie. How can I resubmit or save a session cookie? If there are any errors in the above code, please enlighten me.

Any other ideas would be appreciated.

The most likely problem is that you seem to think that the final assignment in your method ( method = theMethod ) has an effect outside of loadHttp302Request . ( edit : the source code had this statement, but OP changed it later)

This is not true.

Java does not have semantics on demand, so an assignment does not have a pure effect. If you want to save the answer (most importantly, cookie) for the next call, you need to return theMethod and use it the next time. Sort of:

 private HttpMethod loadHttp302Request(HttpMethod method, HttpClient client, int status, String urlString) throws HttpException, IOException { // code as before return theMethod; }
