How to control port 80 traffic?

Dear mates,
the scenario iam trying to implement is the following:

  1. The client opens his browser
  2. If the client tries to browse any webpage (the replied page should be a page i want to show)
  3. if the client tries to refresh or open another webpage he shall get his requested page

so what i shall i do to implement this?

Thank you in advance

Cordially,

Bill

The easiest option is to use the Hotspot system with a login.html that immediately redirects to “/login?username=VALID_USERNAME&password=VALID_PASSWORD&dst=http://page.you.want.to.go.to” to automatically log the user in without any action on his side, and then redirecting to the specified URL on successful login. The wiki and manual contain details about how to set up Hotspots.
