apache build

Hi eveyone, I am in desperate need of help to understand the configuration when using ./configure to install apache 2../configure --prefix=/usr/local/apache --enable-soI understand what the prefix does, its the module theory.>From my understanding --enable-so, enable shared objects.So correct me if i'm wrong I can now, in the httpd.conf load a module via, for example:LoadModule php5_module modules/libphp5.soBut then there are commands such as:--add-module=module_type:/path/to/3rdparty/mod_foo.c --enable-module=shared&--enable-module=sharedWhat do each of these do?Why would I ever need this if I have used --enable-so ?I installed PHP using ./configure --enable-so and everything worked fine.Also where does apxs come into it all?When I configured PHP I used:./configure --with-apxs2=/usr/local/apache/bin/apxsI don't really understand what this means?Many many thanks to anyone who can help with this!
