[mp2] custom configuration not initialised via SERVER_CREATE

[Richard Leopold <mo...@leo.0n3.org>]

MOIn !

The documentation explains how to do "Apache Server Configuration
Customization in Perl" and the SERVER_CREATE/DIR_CREATE mechanism
to set defaults. 

But it only does work, if a customised directive would be be found
in the configuration. Just calling 

	Apache2::Module::add(__PACKAGE__, \@directives);

is not enough to create a initial configuration via the given 
*_CREATE -method of __PACKAGE__

below I'll give you an example test.

Any suggestions or hints to get an initial configuration while 
loading the __PACKAGE__ ? - or is it a bug ?

Regards - Richard


## my http.conf has the lines

PerlLoadModule  kit::BaseConfig_XX

# remark/unremark the following line to show the effect ...
MOI_TestDefaultXX x

# lynx this location 
<Location "/kit/XX">
SetHandler modperl
PerlResponseHandler kit::BaseConfig_XX

## Here comes the test-module
