Câu 59: 301B: BIG-IP Local Traffic Manager (LTM) Specialist Maintain Troubleshoot

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:Request:GET /cart/updatecart.php HTTP/1.1Host: www.example.com -Connection: keep-alive -Cache-Control: max-age=0 -User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-EncodinG. gzip,deflate,sdchAccept-LanguagE. en-US,en;q=0.8 -Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3CookiE.
