How to configure Mod_cluster to return 500 in stead of 404 when JBoss not up?

Solution Verified - Updated -


We use a Apache - modcluster - JBoss setup. We saw that we get a different http error code when the JBoss workers are in error state (503 service temporarily not available) versus when JBoss is stopped normally (404 page not found), as the JBoss proxypass is not available and Apache tries to find the the JBoss page in its document root.
Is there a possibility to have Apache return the same error code?
