Just start a session by default for any user. Once the user has logged in, create a new session or simply write new values to it.
When the user requests a page, some code of yours must be evaluating whether a login is necessary. Ergo, the URL is known to your script. So, you can then write the URL to the session and pick it up after redirecting to login. I'm only vaguely familiar with CodeIgiter but CakePHP can do this automatically. Perhaps you should check to see if CI has the same functionality. On Sat, Dec 19, 2009 at 8:42 PM, Vik <v...@mindspring.com> wrote: > There is no session yet; the user has not yet logged in.
