What I did :
- site is online, I'm not loggued
- I write 
$conf['site_offline'] = '1';
  at the end of my setttings.php
=> site is still online on homepage (even with flushing browser cache), but is offline on another page not displayed before
- conf['site_offline'] = '0';
- site is still offline until I ask for another page (node/xxx not displayed before)

if I do (directly in mysql, not in php code)
TRUNCATE TABLE cache_page;
just after changing $conf['site_offline'] in settings.php (and before asking any page), it works fine, so I guess that
online/offline pages are cached, so just changing $conf doesn't change anything for web client, until caches are cleared.

Pb is that drupal_flush_all_caches() function isn't yet definded in settings.php, so just changing something in settings.php
can't toggle the site online/offline.
It's not a big pb, I will write a little mysql script to put all drupal websites online/offline, I just thought changing
settings was enough.

Thanks for help anyway (I learnt something about string storage in variable table).
