Consider this scenario:

• You're running two or more different websites/applications within a mod_perl process.
• Both applications use a common module (eg a form validation module)
• Each website wants a different "base configuration" for said module (eg the list of permitted HTML tags)
• The module is used in many places throughout the code, so you don't want to have to pass in the configuration every time you call new().

Where do you store this base configuration for each application?

My approach to this has been something like this:

    --------------------------------------
    package Form::Validator;

    my %Config;

    sub set_config {
        my $class    = shift;
        my %settings = @_;
        @{$Config{$class}}{keys %settings} = values %settings;
    }
    --------------------------------------

Then in each website/application, use a subclassed version of this module:

    package Website1::Form::Validator;

    use base 'Form::Validator';
[download]

Do you see any flaws with this approach? Can you suggest a better way of doing this?

thanks

Clint
