Hi all,
Just started with Vaadin Touchkit and want to create an application which shows the user some information based on his profile settings.
I need a way to identify which user is requesting the information so I can present him/her the information which is suited for his interests. In order to do so I need the user to identify himself.
Does anyone have an idea on how to uniquely identify the user ? An email address is enough for me because this is unique but I need to store it somewhere on his/her device and send it with the request to my server.
I’ve tried using a Cookie but somehow the information is lost when the browser is closed on the device. From the documentation it seems there is no option to “never expire” a cookie.
Can someone give me an example in Vaadin Java / Touchkit or point me in the right direction ?
Thank you in advance.
Richard
