[Sessions] Issue with displaying data

[eluser]nl_vinyl[/eluser]
Hi,

I have an application where a user can submit a form with work related data and send this to his/her manager. This data is stored in a DB and given a unique ID.

This unique ID is send thru email to the manager.

A URL can look like: http://domain/fetch/0123dfkjb49tsdfw352

If you click the link the ID is checked and the data is fetched and stored in a session and you are redirected to a view.

The problem is that when a manager opens a second like, the old information is shown (from the previous link). Only after a browser screen refresh the new data is show.

I tried removing session data, unsetting it but nothing seems to work. Any idea what is causing this?
