Browser detection outside AppSuite
AppSuite detects the client browser and collects some information about the current device the visitor is using. This information is used to serve the appropriate UI and enable/disable certain features for the visitor's device.
The browser detection is done by a standalone, dependency free lib that can be included via script-tag to other sites. The original AppSuite login page performs this browser detection. But if you use a form-login and jump directly into AppSuite, the user will miss the warning where AppSuite statesthat an unsupported browser is used.
To show the same warning to a user without using the original AppSuite login page, you should include the browser detection lib in your own login page. That way you can show a warning to the user if they do not use a supported browser.
Including the browser.js lib
The lib is located in the AppSuite UI under http://somedomain.com/appsuite/src/browser.js. Add this script tag to your page head
In your page onLoad you can then call the the global function isBrowserSupported which returns a boolean. If false is returned by the function you should show a warning to the user that his browser is not supported.
