Offline Cache? [message #800581]

Hi there,

is there any support in RAP for caching the application or any data for
offline usage?

We have a requirement that end-users need access to certain web pages
for about three days after a network connection broke down.

I understand that with HTML5 it is possible to store data locally on the
Web-Client. Is there any such support within RAP?
Or any planned support in the future?

Cheers,
Hauke

Hi Hauke,

no, there's no offline support currently in RAP. We have some ideas
about this but no actual planning yet.

But we're currently working on a new feature called "clientscripting"
which will allow you to process events on the client side by providing
some simple JavaScript functions. With this feature, which will be
available for RAP 1.5, you should be able to access an HTML offline
store and do some basic wiring on the client side. However, once a
request is sent to the server the client will still break if there is no
connectivity, and some widgets don't really work without server
interaction, e.g. when a Table is scrolled, the server is involved.

However, I believe that partial offline capablities would be a great
feature for RAP and we should look into it some more in the future!

Best Regards, Ralf
