BThe request will hang and never complete
CThe request will complete immediately without logging
DThe request will be redirected to an error page
Step-by-Step Solution
Solution:

  1. Step 1: Understand the role of next.handle()

    next.handle() passes control to the next handler in the chain.

  2. Step 2: Consequence of omitting next.handle()

    Without calling it, the request processing stops and hangs indefinitely.

    The request will hang and never complete -> Option B

    Missing next.handle() = Request hangs [OK]
Quick Trick: Always call next.handle() to continue request flow [OK]
Common Mistakes:
  • Thinking request completes without next.handle()
  • Expecting syntax errors instead of runtime hang
  • Assuming automatic error redirection
