This is what I did to integrate the Help stuff that comes with AIX into
the normal Apache web server.  Presuming you have Apache already installed
and running normally,

   cd /usr/HTTPServer/conf
and modify httpd.conf to add a VirtualHost stanza as follows:

   Listen 80
   Listen 8080
   <VirtualHost :8080>
      DocumentRoot /usr/docsearch/html
      ScriptAlias /cgi-bin/ /var/docsearch/gi-bin/
      ScriptAlias /icons/ /usr/docsearch/html/
   </VirtualHost>

Then  /usr/HTTPServer/bin/apachectl graceful

-----------------------------------------------------------------------------
I also had to putz around with the configuration a bit.  For example, some
environment variables get set in /etc/environment when you go through
   smitty web_configure
or the long way is, smitty, then select
   System Environments
   Internet and Documentation Services
   
Namely,
   DEFAULT_BROWSER=netscape
   DOCUMENT_SERVER_MACHINE_NAME=localhost
   DOCUMENT_SERVER_PORT=8080
   CGI_DIRECTORY=/var/docsearch/cgi-bin
   DOCUMENT_DIRECTORY=/usr/docsearch/html

Invoking the docsearch program, calls /usr/docsearch/docsearch
                          which calls /usr/bin/defaultbrowser
to call the default browser.  The problem was when the DEFAULT_BROWSER
environment variable was set to just "netscape", that is, not fully-qualified,
if I were cd'd into my aixnotes directory where there exists a non-executable
netscape file, /usr/bin/defaultbrowser did the wrong thing.  I had to change
/etc/environment to be
   DEFAULT_BROWSER=/local/bin/netscape

I also had to change my /local/bin/netscape front end to pass along any
parameters 'cause /usr/docsearch/docsearch called Netscape with a beginning
page to start at as its first parameter.
