Exam 301b topic 1 question 90 discussion

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

GET / HTTP/1.1 -

Host: www.example.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 -

HTTP/1.1 200 OK -
Server: Apache/2.2.15 (Unix)
Last-ModifieD. Wed, 12 Aug 2009 00:00:30 GMT

Accept-Ranges: bytes -

Content-LengtH. 1063 -

X-Cnection: close -
Content-TypE. text/html; charset=UTF-8

Vary: Accept-Encoding -

Content-EncodinG. gzip -

Connection: Keep-Alive -
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 header field is contributing to the issue?
