[Zope] Checking the state of a database connection

How does one check to see if a database connection is up and running? What I want to do is check to see if the connector is connected. If not, redirect the browser to another page. I tried a try/try but didn't seem to catch the exception. Also, can you put a redirect command in the standard_html_header? I tried this and it was ignored. ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.com/dynamo - The Homebuilt Dynamo http://www.compkarori.com/dbase - The dBase bulletin
