Is apachectl restart safe for connected users and sessions?

I made some configuration changes to the log format.
I'd like to restart the web server, but people are currently
access the web server -- including clients relying on
PHP scripts with session cookies.

Can I restart the web server without killing the sessions?

I'm pretty sure the answer is "yes" since all restart does it send a SIGHUP
signal to httpd. Can anyone confirm or deny this?

not with apachectl restart, it might kill some open connections.

for minimum impact try apachectl graceful
