Order of execution of modules in a particular phase is set during
a configure, modules which are last in HTTP_MODULES are executed
first.

That is, if you want to add "module1", "module2", and "module3",
all of them use the access phase, and each of them does something
like

HTTP_MODULES="$HTTP_MODULES moduleN"

in it's "config" file, you should do something like

./configure --add-module=module3 \
--add-module=module2 \
--add-module=module1

to get the "module1 -> module2 -> module3" order.

Note that it may non-trivial to, e.g., make sure your module is
called after standard modules in the access phase.
