Debugging Apache 2

[josef.zellner]

Hi all! 
Following situation: I need to debug a bigger apache httpd 2 module... Currently I 
am using Apache Httpd 2.0.44... 
 
My biggest problem is to start Apache as a single process. How can I tell apache 
to start only one process, because I do not know how to debug a child process (or 
several child processes). 
 
Thanks in advance, Josef
