Which qualifier is used to configure the Content filter action to modify the HTTP header of an HTTP Request?

• A. Error Code
• B. Add
• C. Forward
• D. Corrupt

Answer: (D)

Content filtering qualifiers define how the policy acts on HTTP traffic when a match is found. To alter the HTTP Request headers, you need a qualifier that changes the header content itself rather than simply forwarding or appending data. The Corrupt qualifier is the one designed to modify the header by altering its content, which directly changes what the server sees in the HTTP header.

The other qualifiers behave differently: Error Code targets error handling, Add would introduce a new header line but doesn’t guarantee modification of existing header values, and Forward simply passes the request along without changing the header. So the qualifier that enables modifying the HTTP header of a request is Corrupt.
