Request Object Work Flow - is_initial_req, is_main, main

[Gary C. New]

I am very near in completing a module that allows one to dynamically 
re-map Apache's DocumentRoot directive based on a given URI.

I've been able to get past several obstacles, but am having a very 
difficult time understanding the request object work flow.

My problem seems to be due to subrequests not being mapped properly.

The initial request seems to map as it should, but subrequests are 
randomly mapped or not mapped at all.  I can reload the same page and 
get different subrequests to map, while the previously working 
subrequests no longer map.

My only thought is that it is due to my lack of understanding of the 
request object work flow.

Any basic pointers or examples that could give me a better understanding 
of this process would be greatly appreciated.

Sincerely,

Gary
