You can check which cookies the client sends to LTM using an iRule which logs in HTTP_REQUEST: 


when HTTP_REQUEST {

   log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] request to [HTTP::host][HTTP::uri]"
   foreach cookie [HTTP::cookie names] {
      log local0. "[IP::client_addr]:[TCP::client_port]: Cookie $cookie = [HTTP::cookie value $cookie]"
   }
}

To log the cookies in the response, you could use something similar:

when HTTP_RESPONSE {

log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::status] response with Set-Cookie headers: [HTTP::header values Set-Cookie]"

}

For details on cookies and where browsers store them, you can check these sites:
