A servlet is a Java programming language class that can be used to extend the capabilities of servers that host applications that can only be accessed by a request-response software product. While servlets can respond to all types of requests, most are used to extend applications published by web servers.
Servlet technology is believed to be used to create web software (it resides on a slave server and can create a dynamic web page).
Servlet technology can be characterized as robust and scalable because Java is a language. Prior to the CGI servlet, a scripting language (Common Gateway Interface), such as a server-side programming language, was common. However, this technology now had many disadvantages. We have discussed these disadvantages below.
The Servlet API has many interfaces and classes such as Servlet, GenericServlet, HttpServlet, ServletResponse, servletrequest, etc.
What Could A Servlet Be?
Servlets are Java programs that run on a web forum or are Java compliant application server. They are used to process the request generated by the web server, to process the request, to provide you with a response, and then to send the response back to the web server. The properties related to servlets are as follows: Servlets do server-side work.

What Is The World Wide Web Application?
A web application is an application available on the Internet. Web Usage consists of Web Components that value JSP, Servlet, Filters, etc., and other properties like HTML, CSS, and JavaScript. Web components usually reach the web server and respond to an HTTP request.
CGI (Common Gateway Interface)
CGI technology allows a Web site to call an external program, and even typically pass HTTP requests for information to an external program to process the petition. A new process is started for each request.
Disadvantages Of CGI
- As the number of referring customers increases, it will take a long time to send a response.
- It initiates the process for each proposal, and cyberspace is limited toinitiation of processes.
- The platform uses a dependent language such as C, C ++, Perl.
Benefits Of Servlets
Servlets have many advantages from a CGI perspective. The web container creates an email to handle multiple requests sent to the servlet. Threads have many advantages over such processes, because these companies share a common area of memory, in practice, the cost of communication between subjects is low. The advantages of a servlet are as follows:
- Improved performance: Because the issue creates a chain to call, each one is not addressed.
- Portability: because it uses Java language.
- Reliability: The JVM handles servlets, so I don’t have to worry about memory leaks, garbage collection, etc. Because
- Security: Java is used at home.

Every time the web server receives a call, the servlet container creates HttpServletRequest objects and therefore HttpServletResponse objects. The HttpServletRequest object controls access to the information in the request, and the HttpServletResponse object allows the organization to format and modify the main HTTP response before sending it to the entire client.
Servlet. HTTP servlets provide a service method that instantly forwards a request to another process in the servlet, depending on the HTTP forwarding method used. So, for HTTP servlets, replace doPost () for handling POST requests, doGet () for handling GET requests, and so on.
