Yup... and with apache22, one of the benefits is that the PHP file
handler lines are automatically filled in when compiling PHP (although
I assume that would be the case with any version of apache as well).

Right: that's not from the httpd.conf file itself any longer; it's the
httpd-vhosts.conf file, which is called on as an include in the 2.2
version of httpd.conf.  In earlier versions, the VirtualHost
directives have been moved from the main config file to that include
file.  And the IP/port specification for each VirtualHost entry must
now match that of the NameVirtualHost entry (as shown above).

I triple-checked the config to make sure apache is loading the correct
config file.  In fact, I've finally gotten the config to the point
where none of the apache self-tests report any syntax or configuration
errors at all.  Unfortunately, that doesn't mean it works as I'd
expected; just means there are no syntax errors.

Please find my httpd.conf and httpd-vhosts.conf files attached (didn't
want to clutter the list) in their current states.  Let me know what
you think?

Thank you,

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/foo.log"
# with ServerRoot set to "/usr/local" will be interpreted by the
# server as "/usr/local//var/log/foo.log".

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "/usr/local"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
