When we surf the Internet, a two-way communication takes place between our web browser (client) and a web server (server). To regulate this communication, there are some protocols among which the most common one is the HTTP protocol, where the browser sends an HTTP request to the server and then the server returns an HTTP response to the browser.On the basis of the type of response sent to the browser, we can classify the webpages into two categories: Static webpage and Dynamic webpage.Read through this article to find out more static and dynamic webpages and how they are different from ...

In order to implement some set of restrictions over their communication some set of rules and regulations are defined which are known as web-services which basically defines the format and type of data that need to be exchanged and specifically a contract which both machines should be aware of before taking part in communication.This communication system can be categorized into two types, namely Simple Object Access Protocol ...

When we send a request to a server, the Servlet processes that request, and ... Read More
