What is a Servlet?
A servlet is a Java class used to extend the capabilities of servers hosting applications accessed by means of a request-response programming model. It is commonly used to generate dynamic content on web pages, process and store data received from a web browser, and more. Servlets are used in applications such as content management systems, online banking, e-commerce applications, and more.
What Information is Received by the Web Server?
When a request is made for a servlet, the web server receives the request along with the associated data. This includes the URL of the requested servlet, the HTTP method used to make the request (such as GET or POST), the HTTP headers, and the request body. The request body may contain the data sent by the client, such as parameters, form data, and more. Additionally, the web server receives the IP address of the requesting client, the user agent string, and the language preference of the client. The web server also receives information about the web application, such as the application’s context path. All of this information is used by the web server to process the request and generate the appropriate response.
In conclusion, when a request is made for a servlet, the web server receives a variety of information. This information includes the URL of the requested servlet, the HTTP method used to make the request, the HTTP headers, the request body, the IP address of the requesting client, the user agent string, and the language preference of the client. All of this information is used by the web server to process the request and generate the appropriate response.
