Where to use ASP?

In this article we show some places where we can use ASP.
1- Displaying alert box:
Displaying a small window at client side is done using JavaScript but you can use ASP to control the content of this small window or showing it or not at first place.

2- Data validation:
Data validations for example: entering a character in age parameter text box cause an error message to appears. Validation can be done at client slide using JavaScript or at server side using ASP. This is based on the requirement of the web application. Validation at server side take more time than client side and this must be taken into consideration especially on high hits websites

3- Application logic : Example - User Authentication :
Most of the application logic requirements should be implemented using ASP. The web application asks the user to enter (username/password), these inputs is sent to web application and ASP is ran to verify the user using members table and from that we can say it is login or not. The successful login message is send back using ASP scripting.
