An LTM Specialist needs to rewrite text within an HTML response from a web server. A client is sending the HTTP request below:

GET / HTTP/1.1 Host: www.f5.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-LanguagE. en-US,en;q=0.5 Accept-EncodinG. gzip, deflate Cache-Control: no-cache Connection: keep-alive CookiE. somecookie=1

Although a stream profile has been added to the virtual server, the content within the HTTP response is NOT being matched, and therefore NOT modified.

Which HTTP header should the LTM Specialist remove from the request to ensure the content can be matched and modified?

A. Connection

B. Accept

C. Cache-Control

D. Accept-Encoding
