What does URL routing in SFCC control?

URL routing in Salesforce Commerce Cloud (SFCC) primarily manages how the application interprets the complex set of paths that a user might enter into a web address. The main function of URL routing is to map these URLs to specific controllers and actions within the Commerce Cloud framework.

When a user enters a URL, the routing system analyzes that URL, identifies the relevant controller handling requests for that specific path, and subsequently determines what action or response should be executed. This allows developers to create a clean, semantic, and user-friendly URL structure that is essential for both usability and SEO.

The other options, while related to web applications, do not accurately define the core purpose of URL routing in SFCC. For instance, the design and layout of URLs is a separate concern that typically involves conventions for structure, not the routing mechanism itself. Similarly, retrieval of server data and the storage of customer session data are functionalities that fall under different aspects of application management and data handling, rather than URL routing. Thus, the mapping of URLs to specific controllers and actions is the definitive function of URL routing in SFCC.
