Subject RE: [users@httpd] Restart without disconnecting clients

apachectl -k graceful

The USR1 or graceful signal causes the parent process to advise the children
to exit after their current request (or to exit immediately if they're not
serving anything). The parent re-reads its configuration files and re-opens
its log files. As each child dies off the parent replaces it with a child
from the new generation of the configuration, which begins serving new
requests immediately.

Subject: [users@httpd] Restart without disconnecting clients

     On Linux, can we make Apache (2.0.50) re-read and apply new
configuration (new virtual host, changed IP of a existing virtual host, etc)
without disconnecting the existing clients for whom there is no
configuration change? same is needed for ssl connections.
Has anybody worked on this scenario?
