    If there's some content on server1_apache:port/app_page that can be used to determine the health of the application server, then this could be done. So for example if you setup a page on your app server as /app_page/health and populate it with something that accurately reflects the health of your application, then you could use an HTTP monitor to run a GET /app_page/health and set an appropriate receive string.

If I understand this correctly you will want to setup an additional monitor for the App server directly and then apply this to the pool member. so basically you perform your http check against apache server and also perform a app healthcheck against the app server and have these two healthchecks required for the apache node to be marked up.

 

this way even is apache is up but your app is down the F5 will mark the apache server down due to the Healtcheck requirement that both monitors be successful.
