Question 66
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?

Question 68
An LTM Specialist has a OneConnect profile and HTTP profile configured on a virtual server to load balance an HTTP application.
The following HTTP headers are seen in a network trace when a client connects to the virtual server:
Clientside:

User-Agent: Mozilla/5.0

Question 69
An LTM Specialist has configured a virtual server for www.example.com, load balancing connections to a pool of application servers that provide a shopping cart application. Cookie persistence is enabled on the virtual server. Users are able to connect to the application, but the user's shopping cart fails to update. A traffic capture shows the following:
