In URL policy expressions, which function checks if the URL path starts with a given string?

• A. HTTP.REQ.URL.STARTSWITH("mytraining")
• B. HTTP.REQ.URL.ENDSWITH("mytraining")
• C. !(HTTP.REQ.URL.ENDSWITH("mytraining"))
• D. HTTP.REQ.URL.CONTAINS("mytraining")

Answer: (A)

When you need to match a URL path by its prefix, you use the STARTSWITH function on the URL path. The expression HTTP.REQ.URL.STARTSWITH("mytraining") returns true for any request whose path begins with that string, making it ideal for routing or applying policies to all paths under a specific prefix like /mytraining. This is more precise for prefix checks than testing the end of the path or checking for the string anywhere inside the path. The other options either look at the path’s end or search for the string anywhere in the path, which doesn’t guarantee a prefix match.
