Most of the scripts (or logics) can be placed and execute within the browser or at the client side. However, there may be time that some logics doesn't need to interact with user via web page. Or, some critical logics need to be running at all time regardless which page user is viewing and even when browser is closed. These scripts can be run from server side and they can perform most efficiently especially when scripts need to access server tag values.
On top of standard JavaScript function, IntegraXor comes with a few additional functions for server relevant execution. Two most commonly used functions are getTag('tagname') and setTag('tagname', data) .
