Session Inactivity and browser reset

Controlling browser behavior like the back button is considerably difficult, so while you may be able to redirect away from the screen, it may not prevent going back to previous content. Here is a VERY simple script that injects a JavaScript timer into every response page. The timer restarts on every page load, but DOES NOT account for activity within the browser (mouse movements, etc.) so you'll need to modify it for that. This is just an example of how to inject the JavaScript:

when HTTP_REQUEST {
     STREAM::disable
     HTTP::header remove "Accept-Encoding"
} 
when HTTP_RESPONSE {
     if { [HTTP::header value Content-Type] contains "text" } {
          STREAM::expression {@@@}
          STREAM::enable
     }
} 

Apply a blank Stream profile to the virtual server for this to work.
