Question

A customer must intercept every redirect that its application sends to clients. When a redirect matches, the customer must log a message that includes the client IP address.

Which iRule should be used?

A when HTTP_RESPONSE { if { [HTTP::is_3xx] } { log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]" } }
B when HTTP_REQUEST { if { [HTTP::is_301] } { log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]" } }
C when HTTP_REQUEST { if { [HTTP::is_redirect] } { log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]" } }
D when HTTP_RESPONSE { if { [HTTP::is_redirect] } { log local0. "redirecting client ip address [IP::addr [IP::remote_addr]]" }

Explanation

HTTP_RESPONSE runs when BIG-IP parses the status and headers of the application’s response. HTTP::is_redirect returns true for redirect responses, including 301, 302, 303, 305, and 307, allowing the rule to log the client address for each matched redirect.
