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 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?

why do you want to pollute the internet with SEO keywords? – pQd Nov 2 '12 at 8:44
not pollute, I just want to show some content – rubo77 Nov 2 '12 at 9:35
SEO surely sounds like polluting/vandalism. – pQd Nov 2 '12 at 9:36

A solution with javascript:

create a page called


HTTP/1.0 200
Content-Type: text/html; charset=utf-8

sorry, the site is currently down for maintenance.<br>
document.write('<iframe src="'
        +'" style="width:100%;height:95%"></iframe>');

and set up a temporary server with

$ apt-get install ucspi-tcp
$ tcpserver 80 sh -c 'awk "/^\r*$/ { exit }"; cat offline.html'

but it seems google doesen't allow such a link in an iframe, so another cache will be needed.
