I would like to set all virtualhosts on my server down for maintenance for some time.

The temporary page should contain something like

sorry, the page www.xxx.com is down for maintenance. you can see the cached version here:

Then the trick: the user should then see the cached page from a cache like googlecache or similar for the requested page as long as the server is down.

This would show the correct content on pages, that are static anyway and give the visitor the needed content in many cases, while I can shut down mysql and other services that would usually be needed to show that pages.

How can I set a global page on all virtualhosts, that parses the original requested URL through PHP?
