What is the purpose of Request Filtering in IIS 7.0?

• A. It restricts certain URL sequences or file types to protect against harmful requests.
• B. It logs all requests to an external system for auditing.
• C. It automatically compresses responses to save bandwidth.
• D. It translates URLs to a different language.

Answer: (A)

Request Filtering in IIS 7.0 is about screening incoming requests and denying those that match defined patterns, such as dangerous URL sequences or disallowed file types, to protect the server from harmful requests. It inspects the request path, query, and headers and drops any request that fits the rules before it reaches your application. This helps prevent things like directory traversal or requests for potentially dangerous file types. It’s not about logging, compressing responses, or translating URLs—that’s handled by other features.
