Session Data

I'm wrapping up an MVC implementation for PHP. Everything is working splendidly except that redirects seem to be loosing session data. Here is the basic logic 1) on a form, user enters data hits submit 2) data validates OK, data is saved and $_SESSION['MVC_message'] is set to 'Save was successful' 3) After setting session data in step 2 above, a redirect is issued: header('Location: ' . $url); 4) The URL represented by $url within same app doesn't have any data in $_SESSION and I'm positive a session_destroy() isn't being called explicitly. The ideas here is to show a page with context information for the user. Any ideas why this isn't working? -- Tony Bibbs "I guess you have to remember that those who don't tony@tonybibbs.com hunt or fish often see those of us who do as harmlessly strange and sort of amusing. When you think about it, that might be a fair assessment." --Unknown
