title: Check for live Data Source Name Before proceeding
body: <p>Would it be ok to get a CF app to check for a valid database before proceeding to process that request?</p>
  
  <p>This is because there may be instances where the database server may be down or being upgraded, hence an error comes when a db dependant request is made.</p>
  
  <p>If there is no connection to the db server, the user can be safely redirected to a safe page.</p>
  
  <p>Or can cfcatch work?</p>
  
  <p>How can this check be done?</p>
  
  <p>Thank you.</p>
