Develop a multisite solution

In a multisite solution, you need to decide whether the sites can share the same code base and if there is content that the sites cannot share.

What is multisite?

Optimizely Content Management System (CMS) can host multiple websites using a shared database and the same content assets. You can add sites from the CMS admin view, and the start pages will share the same root page in the content structure. See Set up multiple sites.

In DXP, sites use the same Web App and share the same code base and Optimizely Search & Navigation index. You can have an unlimited number of sites in the Web App. Common scenarios include solutions for the fashion industry, where sites may share the same content types and controllers. Still, each brand uses different views and styles, resulting in different outbound presentations.

Development strategies

Code base

Consider how to organize your code using standard conventions and site-specific structures. Can the sites share the same code base, or do you need to separate them? Can you work with shared models and controllers but use different views?

Content types

• Restrict blocks to a single site or share blocks across sites. Limit the number of site-specific content types (pages, blocks, media) if possible.
• Limit access to specific content types using roles or permissions and the AvailableContentTypes attribute.
• Limit the ability to add content using the AllowedTypes attribute on content areas.

Note

Editors with access to multiple sites will have access to all.

Display channels or options

Defined display channels and display options are available across sites. Consider how to manage these if different websites have different requirements. For example, you can use TemplateResolver to detect which template should be active for a specific site.

Forms

Forms in a multisite solution are available for selection across sites. To restrict access to forms, you can apply access rights on form folders, just as you do for other content items. You can also create a specific virtual role for managing forms.

Categories

Optimizely offers built-in categorization functionality to tag content and build features based on this. Categories are shared between sites in a multisite solution. You can organize categories by site in a hierarchical structure or build your own category system.

Personalize

Added audiences are available for sites in edit view. You can create a specific role for managing audience criteria (optional) and ensure that editors working with content personalization are included in the group and well aware of which audiences to use in what context.

User access

If different editors administer sites in a multisite solution, you can set up site-specific groups to access editing in selected parts of the shared content structure. See access rights in the Optimizely user guide.

Search

While available for on-premises versions of Optimizely,Lucene.NET is not supported with DXP. Instead, Optimizely Search & Navigation provides advanced features that should be leveraged in your search implementation.

Sites with Optimizely Search & Navigation share the same index, and optimizations apply to sites. Each site has its partition of the index and a shared partition for shared content. You can view search results and statistics per site or across sites and limit search results per site.

Localize

When translating user interface texts using the built-in localization service, you can create one or more XML files with any name in the ~/Resources/LanguageFiles folder.

📘

Note

Content types may have the same class name in code, using a different namespace and class name. To ensure that users can differentiate these, use unique DisplayNames. See Localizing the user interface.

Custom cultures

Custom cultures, such as sv-gb and en-fr, are currently not supported for solutions running in Optimizely DXP. Cultures are part of the standard operating system and require changes to the registry to modify or add them. This modification is not allowed by the Azure App Service.

See the blog post Implementing custom cultures, CultureInfo, localize Azure App Service for information.

Apps (add-ons)

Installed apps (also known as add-ons) are available across sites. However, you can restrict access through configuration by setting access rights for the location paths.

Debug

You can debug on your local machine and in the Integration environment. Debug in other environments only when needed. See Troubleshoot.
