Question

I’m currently trying to use the current session of a php web page from an applet. I tought it would be straightforward, but it didn’t go as smooth as I tough. From the php man:

session_start() creates a session or resumes the current one based on a session
identifier passed via a GET or POST request, or passed via a cookie.

From there I did some php (simplified here):

// PAGE1.PHP
session_start();
$_SESSION['test'] = true;
echo "sid=" . session_id();

// PAGE2.PHP
session_start();
if ($_SESSION['test'])
    $echo "success";
else
    $echo "fail";

So, from my applet, I do a request to PAGE1.PHP and it returns me the session id. When I do a new request on the page 2, I pass the session id as a parameter and it seems that the session wasn’t kept. I use

URL url = new URL("my/url/PAGE2.php?sid=" + session_id); 
URLConnection conn = url.openConnection();
conn.setDoOutput(true); 
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()); 

wr.write(data); // data is the post data created previously
wr.flush(); 

// Get the response 
BufferedReader rd = new BufferedReader(
    new InputStreamReader(conn.getInputStream())); 
String line;
while ((line = rd.readLine()) != null) { 
    System.out.println(line);
}

I have tried via POST and GET method and it doesn’t seem to work.

So I’m wondering if it’s possible, and if yes, what do I miss?

thanks.

Answer 1

Your PAGE2.php is not actually using the sid param you’re passing via _GET to initiate the session.

In page2.php, try:

session_id($_GET['sid']);
session_start(); 

instead of plain-old:

session_start();
