What is the primary role of a content-switching virtual server?

• A. It routes requests to different backends based on content rules
• B. It terminates SSL connections
• C. It caches responses
• D. It modifies traffic

Answer: (A)

A content-switching virtual server acts as the traffic director at the edge, deciding which backend handles each request by examining the request content. It uses content-switching policies that look at elements like the URL path, host header, or specific cookies to route traffic to the appropriate service group. This enables hosting multiple applications behind a single IP/port, with each application handled by its own backend pool. While SSL termination, caching, and traffic modifications are separate capabilities handled by other configurations, the defining role here is routing requests to different backends based on content rules. For example, a request to /images would go to the image service, while /api would go to the API service.
