Debian names its httpd 'apache2'.

The one you want to touch is the one with PPID 1: that's the parent  
process.

sctemme@surtur:~$ sudo kill -HUP 5692

> $sudo /etc/init.d/apache2 start

sctemme@surtur:~$ cat /var/run/apache2.pid
5692

In other words: a restart as effected by the Hangup signal puts the  
pidfile back.

I would be worried about its disapearance in the first place though.
