need someone to explain compiling Apache modules for apache 1.3.x

[Shaleh <shaleh@livenet.net>]

Hi, do to various issues, I need to compile my own Apache and modules (some
machines here run Debian, other RH, others bsd).  I would like to know how best
to compile Apache so that I can load DSO modules via its conf and also to
compile 3rd party modules when needed (hopefully w/o re-compiling Apache).

Thanks in advance.
