Site definition

A site definition contains site-wide configuration such as navigation, common page areas, and JavaScript that you want to load on every page. A site definition also contains a reference to your theme and defines locales for entering content in multiple languages.

Do I need a site definition?

No, it is not necessary to use a site definition. A site based on concrete template definitions works perfectly well. A site definition is an advanced option. It is useful when you have a large site and want to avoid repeating a similar configuration.

Without a site definition you can still:

  • Choose which templates are available to editors.

  • Add CSS and JavaScript at the page level instead of site level.

  • Configure variations for each page template.

But without a site definition you cannot use:

Prerequisites

You need the Site module in order to create a site definition. The Site module may not always be included, for example, when you create your own webapp based on the empty webapp. Add a dependency to the Site module in your webapp POM file.

DX Core provides the multisite feature. It allows you to configure a different site definition for each website in a single Magnolia instance. Each site can be mapped to a different domain and you can serve content from different workspaces.

These features are in the Multisite module.

For multisite configuration details, see:

Site limitation

In DX Core, the number of sites that can be used is defined by the number of sites purchased.

In the Community Edition, you can only create and use one site.

Configuring a site definition

You configure a site definition in the Site app.

Property Description

templates

optional

For an example site definition, see the travel.yaml definition file in the Magnolia travel-demo repository.

     prototype

optional

The template prototype is a master template definition which applies to the whole site. Anything you configure in the prototype is applied to all page templates.

     availability

optional

Template availability defines which page templates are available to editors in the Pages app. There are more ways to control page template availability.

enabled

optional, default is true

Enables and disables the site definition.

domains

optional

Maps domain names to the site.

Requires the Multisite module (DX Core).

theme

optional

Reference to a theme that defines the look and feel of the site. Themes are configured in config:/site/config/themes.

i18n

optional

Locale configuration and support for entering and serving content in multiple languages.

For more details how to configure this i18n property subtree, see Defining locales for a site.

mappings

optional

URI mappings that define which node in a workspace should be served when a particular URI is requested.

trustedProxyConfig

optional

Configuration of a Trusted proxy headers filter for the given site.

travel
...
  trustedProxyConfig:
    forwardingEnabled: true
    headers:
      xForwardedFor:
        name: x_forwarded_for
        values:
          0: example.com
...

Incorrect filter configuration may block all user traffic.

If access to Magnolia is blocked by an incorrect filter configuration, you can fix this by decorating the site config and overriding the incorrect values.

Filter configuration parameters determine which headers are allowed or checked by this filter.

  • If forwardingEnabled is set to false (default), the filter blocks requests containing specific headers. This is to ensure security when proxy headers are not expected.

    The default setting prevents undesired traffic blocking.

  • If forwardingEnabled is set to true, the filter checks the values of specific headers in incoming requests. Requests with unexpected header values are blocked for security reasons.

Available header names:

  • x_forwarded_for for X-Forwarded-For

  • x_forwarded_host for X-Forwarded-Host

  • x_forwarded_proto for X-Forwarded-Proto

  • x_forwarded_port for X-Forwarded-Port

When using a proxy in front of Magnolia, it’s highly recommended to apply IP filtering in Tomcat so that only requests from the trusted proxy would be processed. For more details about setting IP filtering, see Remote Address Valve.

parameters

optional

Custom template properties that you can access from a script without having to write a class.

variations

optional

Variations adapt the site for different devices or geographical locations.

The Site app is actually a shortcut that displays the configuration from:

  • config:/modules/site/config/site and from any extended locations in a single-site setup (Community Edition, DX Core) * config:/modules/multisite/config/sites in a multisite setup (DX Core)

Site definitions in CE and DX Core

The steps to create a site definition can vary depending on which modules you have installed. In Magnolia Community edition, you are only allowed a single site definition. For Magnolia DX Core, multiple site definitions are allowed. These instructions can be used as a guide for creating a new site definition from scratch.

Community Edition

When using Community edition, only the site module is installed. Therefore, you only have the option for a single definition as community edition can only support one site. Multiple sites would require multiple author instances or an upgrade to DX Core.

DX Core

When using DX Core, only the multisite module is installed. With the multisite module you can have as many sites as required. However, there are physical limits as each new site that is added creates additional complexity. It can sometimes be helpful to break installations into multiple author instances. Especially in cases where you have multiple different teams spanning different regions.

You can have as many author instances as you need as long as the content stays independent.

For an example, see the fallback.yaml definition file in the Magnolia travel-demo repository.
