Disclaimer page shown when first entering section of the site

You could create a webpart or use a custom global event and check the users each time they authenticate. Add a custom field or two (reviewed and reviewed date) to the user object and redirect the user to your "disclaimer" on authentication if they have not reviewed the disclaimer. Then after they read that disclaimer, update the users values.

Thanks, in this case it's not for authenticated users but any user to the site. But it sounds like a custom Webpart is needed, and I can just store the Accepted state to the session details.

Would I still use a custom global event, was thinking along the lines that the Webpart would detect that user hasn't accepted disclaimer, would redirect to a disclaimer page, then if accepted would store the details and then redirect back to the previous page which would now load as normal.

Thanks Paul

For users that are authenticating, a global event handler is probably the best way tot go. But if you're not requiring them to authenticate then a webpart might be better.

There is a Cookie disclaimer webpart already included in Kentico, you might check that out and see if it gives you any ideas on how it's working/storing the data per user.
