Configure the MultisiteMiddleware class locally

For accurate site resolution during local development, developers are encouraged to simulate production-like domain routing by configuring custom hostnames. This can be done using the MultisiteMiddleware.

To set up and configure the MultisiteMiddleware to achieve production-like domain routing locally:

1. Find your hosts file:

   • For macOS/Linux - /etc/hosts
   • For Windows - C:\Windows\System32\drivers\etc\hosts

2. Add the following to point a local domain to 127.0.0.1:

   
   127.0.0.1 sitea.localhost
   127.0.0.1 siteb.localhost
   

3. Update the Site Definition in SitecoreAI:

   • Navigate to /sitecore/content/YourTenant/YourSite/Settings/SiteGroup/Site Definitions.
   • Open the relevant Site Definition item (for example, sitea).
   • Add sitea.localhost to the HostName field.

This ensures consistency between your local development environment and the content served by SitecoreAI.
