creating CGI scripts and interacting with existing ones.

[Mohammed Murphy]

Thanks for the hints Marc. Unfortunately I was not clear enough about my 
requirements before so I will expound a bit more.

I only want to talk about the first issue of creating CGI scripts and 
break it down into two parts. Firstly, I would like to create a web page 
that contains the look & feel and header & footer info of the existing 
pages with my own customised web data in the middle. The important point 
is that I would like it to be automated, because (as I revealed in my 
last email) this is for an installer-type application. So for instance, 
if a Nagios user updates their Nagios system to a newer version with a 
slighly different look & feel, then the same installer-type application 
will still be able to generate the custom page appropriately. Is this 
possible?

Secondly, is the issue of linking to my custom pages from exisitng 
pages. The fact that I want it to be automated means that I require a 
way of informing Nagios that a new custom page exists so Nagios will 
provide a way for the Nagios user to access it via a link on an existing 
page. I thought about parsing and then modifying side.html, but that is 
only reliable if that is guaranteed to remain the same in all versions 
of Nagios. nBoard, for instance, requires that a new html page simply be 
added to an 'extras' directory; so I wondered if the default Nagios web 
UI had a similar mechanism.

Thanks for your time Marc. I hope I clarified my requirements a bit more.
