APM different new session URL

Here's my solution. Be gentle. I'm new here ;-) Any sugegstions for improvement are welcome. Setting the cookie via an irule event in the apm policy would be nice, as well as setting the expiration to a long time.

when HTTP_REQUEST {
    set static::orig_uri [HTTP::uri]
    set static::cookie_name "LandingURI"
    set req [HTTP::request]
    set reload_page {
        
        
        Cookie set for future use.
        
        
        
    }

    switch [HTTP::path] {
        "/" {
            if { [HTTP::cookie exists $static::cookie_name] } {
                log local0. "No URI given, Found cookie. Send Redirect."
                set cookie_value [HTTP::cookie value $static::cookie_name]
                HTTP::redirect "http://$cookie_value"
            }
            else {
                log local0. "No URI given, no cookie found."
             }
        }
        "/Specific" {
            if {!( [HTTP::cookie exists $static::cookie_name] )} {
                log local0. "URI /Specific given, Set cookie."
                set cookie [format "%s=%s; path=/; domain=%s" $static::cookie_name $static::orig_uri "."]
                HTTP::respond 200 content $reload_page "Set-Cookie" $cookie
            }
        }
        default {
            if { [HTTP::cookie exists $static::cookie_name] } {
                log local0. "Non-existing URI given, found cookie. Send Redirect."
                set cookie_value [HTTP::cookie value $static::cookie_name]
                HTTP::redirect "http://$cookie_value"
            }
            else {
                log local0. "Non-existing URI given, no cookie found."
             }
        }
    }
}
