NAME

Apache2::ASP::Manual::ConfigXML - Documentation about the XML config file

DESCRIPTION

One benefit of keeping all of your application's configuration data in one place is ease of maintenance. Anyone who has had to deal with an application that used hard-coded database connection strings, hostnames or file paths would agree that an application can be rendered unmaintainable by poor configuration.

FILE NAME

The default filename of the XML config file is apache2-asp-config.xml

CONTENTS

The following is an example of the contents of apache2-asp-config.xml on Linux:

<?xml version="1.0" ?>
<config>
  <web_application>
    <domain_re>^.*$</domain_re>
    <do_reload_on_script_change>1</do_reload_on_script_change>
    <application_name>DefaultApp</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>@ServerRoot@/PAGE_CACHE</page_cache_root>
    <application_state>
      <manager>Apache2::ASP::ApplicationStateManager::SQLite</manager>
      <dsn>DBI:SQLite:dbname=/tmp/apache2_asp_applications</dsn>
      <password></password>
      <username></username>
    </application_state>
    <session_state>
      <manager>Apache2::ASP::SessionStateManager::SQLite</manager>
      <cookie_domain>localhost</cookie_domain>
      <cookie_name>session-id</cookie_name>
      <dsn>DBI:SQLite:dbname=/tmp/apache2_asp_sessions</dsn>
      <password></password>
      <username></username>
      <session_timeout>30</session_timeout>
    </session_state>
    <settings>
      <!-- lib is required -->
      <lib>@ServerRoot@/lib</lib>
      <!-- the rest are completely arbitrary -->
      <dsn>DBI:mysql:databasename:localhost</dsn>
      <username>my-username</username>
      <password>swordfish</password>
    </settings>
  </web_application>
</config>

The following is an example of the apache2-asp-config.xml file on Windows:

    <www_root>@ServerRoot@/htdocs</www_root>
    <page_cache_root>@ServerRoot@\PAGE_CACHE</page_cache_root>
    <application_state>

      <dsn>DBI:SQLite:dbname=apache2-asp/tmp/sessiontest</dsn>
      <password>j@p@n</password>
      <username>root</username>
    </application_state>
    <session_state>
      <manager>Apache2::ASP::SessionStateManager::SQLite</manager>
      <cookie_domain>127.0.0.1</cookie_domain>

      <session_timeout>30</session_timeout>
    </session_state>
    <settings>

      <password>j@p@n</password>
      <username>root</username>
    </settings>
  </web_application>
</config>

DTD

This is the DTD for the XML config file:

<!ELEMENT application_name ( #PCDATA ) >

<!ELEMENT application_root ( #PCDATA ) >

<!ELEMENT application_state ( manager, dsn, password, username ) >

<!ELEMENT config ( web_application ) >

<!ELEMENT cookie_domain ( #PCDATA ) >

<!ELEMENT cookie_name ( #PCDATA ) >

<!ELEMENT do_reload_on_script_change ( #PCDATA ) >

<!ELEMENT domain_re ( #PCDATA ) >

<!ELEMENT dsn ( #PCDATA ) >

<!ELEMENT handler_root ( #PCDATA ) >

<!ELEMENT lib ( #PCDATA ) >

<!ELEMENT manager ( #PCDATA ) >

<!ELEMENT media_manager_upload_root ( #PCDATA ) >

<!ELEMENT page_cache_root ( #PCDATA ) >

<!ELEMENT password ( #PCDATA ) >

<!ELEMENT session_state ( manager, cookie_domain, cookie_name, dsn, password, username, session_timeout ) >

<!ELEMENT session_timeout ( #PCDATA ) >

<!ELEMENT settings ( lib ) >

<!ELEMENT username ( #PCDATA ) >

<!ELEMENT web_application ( domain_re, do_reload_on_script_change, application_name, application_root, handler_root, media_manager_upload_root, www_root, page_cache_root, application_state, session_state, settings ) >

<!ELEMENT www_root ( #PCDATA ) >
