Scenario: A Citrix Engineer needs to limit Front End Optimization (FEO) on a web application to mobile users with mobile devices. The engineer deckles to create and bind an FEO policy.
Which advanced expression should the engineer use in the FEO policy?
To limit Front End Optimization (FEO) to mobile users, the correct advanced expression would involve checking the 'User-Agent' HTTP request header for typical strings associated with mobile devices. The expression HTTP.REQ.HEADER('User-Agent').CONTAINS('IOS') || HTTP.REQ.HEADER('User-Agent').CONTAINS('Android') appropriately captures both iOS and Android mobile devices, thus ensuring that the FEO policy is applied to mobile users specifically.

HTTP.REQ.HEADER("User-Agent").CONTAINS("IOS")||HTTP.REQ.HEADER("User-Agent").CONTAINS("Android") To limit Front End Optimization to mobile users, the engineer needs to check the "User-Agent" HTTP request header for strings that are typically included by mobile devices, such as "IOS" for Apple devices and "Android" for Android devices. The expression checks if the "User-Agent" header contains either "IOS" or "Android" to apply the policy for mobile users.
