An insurance company has an existing API which is currently used by customers.

When multiple Mule applications need to listen on the same port (e.g., port 443), configuring them individually will cause a conflict because only one application can bind to a specific port on a server at a time. To resolve this, you can use a Mule domain project, which allows multiple Mule applications to share configurations, including HTTP listeners. Here’s how you can do it:

Create a Mule Domain Project:

In Anypoint Studio, create a new Mule Domain Project.

This project will contain shared resources that can be used by multiple Mule applications.

Configure the Shared HTTP Listener:

Define the HTTP Listener configuration in the domain project.

Reference the Shared HTTP Listener in Mule Applications:

In each Mule application that needs to use port 443, reference the shared HTTP Listener configuration from the domain project.

Deploy the Domain Project and Applications:

Deploy the domain project to the Mule runtime first.

Then deploy the Mule applications that reference the shared HTTP Listener configuration.

By using a domain project to centralize the HTTP listener configuration, you ensure that both APIs can listen on port 443 without conflicts, allowing customers to access both APIs through the same port.
