_eventually_ some actual docs @ the site will be helpful, but  for now,

one each.  although the order doesn't make a difference, in the
example following, the 1st invoked app is a single instance of a
pressflow6 site front-page.  The 2nd invoked app is simply the login
page of a drupal6 site.

watching,

	tail -f /var/log/apache/{pressflow6,drupal6}*log error_log access_log

INVOKE THE 1st APP

==> pressflow6.log <==

INVOKE THE 2nd APP ... RETURNS @ BROWSER:
