2. Add the following parameter in the target field just like the following

• C:\Users\Administrator\AppData\Local\Google\Chrome\Application\chrome.exe -user-agent=”Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10″
