Header Action Field Description / Action
Operator Select the HTTP header modify action the ACE appliance is to take in an HTTP request from a client,
a response from a server, or both:
• Delete—Deletes an HTTP header in a request from a client, in a response from a server, or both.
• Insert—Insert a header name and value in an HTTP request from a client, a response from a server,
or both. When the ACE uses Network Address Translation (NAT) to translate the source IP address
of a client to a VIP, servers need a way to identify that client for the TCP and IP return traffic. To
identify a client whose source IP address has been translated using NAT, you can instruct the ACE
to insert a generic header and string value of your choice in the client HTTP request.
• Rewrite—Rewrite an HTTP header in request packets from a client, response packets from a
server, or both.
