Hi,

I would like to know the list of processes that belong to the Apache
Web server, on Unixes and on Microsoft OSes.

I tried to search info about the process level architecture of Apache
but did not find any manuals or papers that deal with that topic,
please point me to good resources.

Thanks,
- Sudhin.

On Linux boxes,

pstree -c `cat /var/run/httpd.pid`

will give you a tree view of Apache and its child processes, such as CGI
scripts. (Other flavors of Unix may offer a command similar to pstree.)

A similar utility for Windows NT/2000/XP is tlist. It came it the
Resource Kit, I think.

it's all httpd. number and owner(s) of these vary with apache version,
os and mpm module.

a good starter is http://httpd.apache.org/docs-2.0/mpm.html and the
descriptions of the different mpm's linked from there. apache 1.3 was
effectively hardwired to use mpm_prefork behaviour on unix etc. and
some kind of threaded thing like mpm_winnt on windoze.
