Mobile Websites More people connect to the Web over slower, mobile networks. The performance of Web pages is now really important. To increase performance we need to serve only the appropriate files for a device. 3 main common ways mobile web interfaces are being built…

Responsive Design Same content page across all devices. Content is referenced by a single URL. Average page size is around 1.3mb. 3G 40% slower, LTE 12% slower than desktop speeds. 80% + responsive sites send the same assets to all devices. Interfaces become complex client-side CSS and JS applications.

Mobile only website Website Content is easier to tailor should the mobile need to provide a different experience. Average page size is around 180kb. Easier to make separate changes to mobile and desktop websites. – Typically different URL and independent page layouts. Redirection required.

REsponsive + Server Side (RESS) Detects devices server side and delivers features that are optimized for the user of that device. Deliver only what a client device needs. Requires an accurate server side detection mechanism.

The SDL Tridion Context Engine Content Delivery Module Provides Context – More than just device device detection – Plugs in wonderfully with other SDL tools For the purpose of this presentation were using it for device detection

Installation and configuration Create the device database: – java -Xms1028m -jar lib\cwd_engine-2011.jar – Java -jar cwd-repository-manager.jar cwd- repository.jar {webroot}/bin/repository/

Installation and configuration Configure the ADF cartridge – Cd_ambient_conf.xml Javascript include Thats it

Test installation Use a webpage to output all claims in the claim store Thanks again Peter

Using it….. Uri claimUri = new Uri("taf:claim:context:device:tablet"); string isTablet = Tridion.ContentDelivery.AmbientData.AmbientDataContext. CurrentClaimStore.Get (claimUri); Context Engine Wrapper Library – rapper/ rapper/ if(context.Device.IsTablet) { message = "you are using a tablet device"; } – Configuration possibilities to create device families

Summary RESS is better solution to Responsive. Most websites are built using responsive. The SDL Tridion Context Engine is a great tool to provide Server-Side detection. – Integrates perfectly with other SDL modules,.Net, Java and other applications. – Not sure about future updates to the device database and how these will be released.
