A web application is a combination of two types of script one is a Server-Side script and the other is a Client-Side script.

Server-Side Scripts (PHP and ASP) to manage the storage and retrieval of the information and Client-Side scripts (JavaScript and HTML) to display information to the users. This provides users to interact with the company via online forms, content management systems, shopping carts, and other tools. Furthermore, the applications enable employees to create papers, exchange information, collaborate on projects, and work on shared documents from any place or device.

 How does a Web Application work?

Web applications are regularly created in a browser-supported language, such as JavaScript or HTML since these languages depend on the browser to create the program executable. Some of the apps are dynamic and must be handled on the server. Others are fully static, requiring no server processing.

Web Server is required to manage client requests and a Web Application Server to perform the tasks requested, and, in certain cases, a database to store the information. Application server technology includes ASP.NET, ASP, ColdFusion, PHP, and JSP.

A common web application flow looks like this:

  1. Web browser or the User is used to send a request to the Net Server utilizing the Internet.
  2. The Web Server transfers this request to the appropriate web application server
  3. Web application Server performs the desired action – such as accessing the database or processing data – and then generates the requested data results.
  4. The Web application Server provides the requested information or processed data to the Web Server.
  5. Web Server responds to the client with the requested information, subsequently shown on the user’s screen.
