Visual LANSA Framework

Frequently Asked Questions
Are AJAX applications secure?

In general internet usage, AJAX applications are not always secure (depending up how they were designed). However, the Framework implementation is secure.

AJAX applications can only be used within Framework managed web sessions.  They can be used over https connections.

 

How do I screen paint my AJAX pages?

AJAX pages are standard HTML documents which can be painted with many different tools, such as Microsoft FrontPage, etc.

However, as you start to do more advanced AJAX applications you will see that static screen painters are really not that useful when dealing with web pages where much of the content is dynamically created and updated by executing JavaScript AJAX code (this is also true of many Windows Rich Client screen painters as well). 

Do I need to backup my AJAX pages?

Yes. It is very important that you do this or you will lose your work.

Do I need to backup my AJAX functions?

Yes, but not independently of your LANSA repository.

Since AJAX functions are just LANSA functions they will be backed up whenever you backup your LANSA development environment.
