=head1 NAME

Apache2::ASP::ConfigNode::Web - The $Config->web object.

=head1 SYNOPSIS

Given the following configuration...

  <?xml version="1.0"?>
  <config>
    ...
    <web>
      <application_name>MyApp</application_name>
      <application_root>@ServerRoot@</application_root>
      <handler_root>@ServerRoot@/handlers</handler_root>
      <media_manager_upload_root>@ServerRoot@/MEDIA</media_manager_upload_root>
      <www_root>@ServerRoot@/htdocs</www_root>
      <page_cache_root>/tmp/PAGE_CACHE</page_cache_root>
      <request_filters>
        <filter>
          <uri_match>/members/.*</uri_match>
          <class>My::MemberFilter</class>
        </filter>
        <filter>
          <uri_match>/checkout/.*</uri_match>
          <class>My::HasOrderFilter</class>
        </filter>
      </request_filters>
    </web>
    ...
  </config>

You would access it like this:

  $Config->web->application_name;           # 'MyApp'
  $Config->web->application_root;           # '/usr/local/projects/mysite.com'
  $Config->web->handler_root;               # '/usr/local/projects/mysite.com/handlers'
  $Config->web->media_manager_upload_root;  # '/usr/local/projects/mysite.com/MEDIA'
  $Config->web->www_root;                   # '/usr/local/projects/mysite.com/htdocs'
  $Config->web->page_cache_root;            # '/tmp/PAGE_CACHE'
  
  You will never need to do this:
  foreach my $filter ( $Config->web->request_filters )
  {
    my $regexp  = $filter->uri_match;
    my $class   = $filter->class;
  }# end foreach()

=head1 DESCRIPTION

Apache2::ASP::ConfigNode::Web provides access to the C<web> portion of the configuration.

=head1 PUBLIC PROPERTIES

=head2 application_name

Returns the name of the application.

=head2 application_root

Returns the absolute path to the root of the application, i.e. C</usr/local/projects/mysite.com>

=head2 handler_root

Returns the absolute path to where the 'handlers' are installed, i.e. C</usr/local/projects/mysite.com/handlers>

=head2 media_manager_upload_root

Returns the absolute path to where uploaded files will be stored, i.e. C</usr/local/projects/mysite.com/MEDIA>

=head2 www_root

Returns the absolute path to where the normal website files (ASP, images, css, javascripts, etc) are located, 
i.e. C</usr/local/projects/mysite.com/htdocs>

=head2 page_cache_root

Returns the absolute path to where 'compiled' ASP scripts are stored, i.e. C</tmp/PAGE_CACHE>

Since the 'compiled' ASP scripts are overwritten whenever the source ASP script has been changed on disk,
the webserver process must have read/write access to this location.

It is recommended that a temporary path is used - '/tmp' on most Linux distributions.

=head2 request_filters

Returns a list of ConfigNodes that represent individual C<filter> elements in the configuration.
