Persistent connections

[Juan Luis de Amaya Robles <Ju...@concatel.com>]

Hi everybody,
 
I tell you:
 
I have two urls to call (PHP pages). One sets a language variable in
session. Another returns data depending on the session var.
 
i think, i need stablish persistent connection to connect web pages with
session data.
 
When i call the first one url, it returns a cookie with a PHPSESSID
(it's a php). ok.
I understand that cookie is sended when I call the second one url, but i
get a incorrect second page, well, the language is not correct.
This is because the session is incorrect. I think.
 
 
What's the problem?
When i print the "isPersistent()" method is returned false. I must
configure anything else?
where the cookie is stored?
 
Thanks a lot!
 
A piece of my code is:
 
// Get HTTP GET method
     GetMethod httpget = new GetMethod(strURL);
                
        // Execute HTTP GET
        int result = httpclient.executeMethod(httpget);
        // Display status code
        System.out.println("Response status code: " + result);
        
        // Get all the cookies
        Cookie[] cookies = httpclient.getState().getCookies();
        
        System.out.println("Present cookies: ");
        for (int i = 0; i < cookies.length; i++) {
         Cookie c = cookies[i];         
            System.out.println(" - " + c.toExternalForm()+", PERSISTENT:
"+c.isPersistent());
        }        
        
        String pag = httpget.getResponseBodyAsString();
        int idx = pag.indexOf("Welcome");
  if (idx >= 0){
   System.out.println(pag.substring(idx,idx+200));
  }else{
   System.out.println("No encontrado!");
  }
        // Release current connection to the connection pool once you
are done
        httpget.releaseConnection();

No. If connections were persistent, you wouldn't need a session.

Quite possible. Make sure you use the same HttpClient object for both 
requests.
Check out our cookie guide to see whether your problem is addressed there:

http://jakarta.apache.org/commons/httpclient/cookies.html

HttpClient never stores persistent cookies anywhere but in memory.
By default, they are put into the state of the HttpClient object.
Make sure you use the same HttpClient object for both request. Don't
pass an explicit state to the second request. Try the "browser
compatibility" cookie spec, since some servers send domain names
without a leading dot.

hope that helps,
  Roland
