Which of the Following Functions Are Done by Web Server?

A web server is a crucial component of the World Wide Web infrastructure. It plays a vital role in handling various functions and delivering web content to users. In this article, we will explore the different functions performed by a web server.

Handling HTTP Requests and Responses

One of the primary functions of a web server is to handle HTTP requests and responses. When a user requests a webpage by entering a URL in their browser, the browser sends an HTTP request to the web server. The web server then processes this request and sends back an appropriate response, which may include HTML, CSS, JavaScript files, images, or any other type of data requested by the client.

Hosting Websites

A web server is responsible for hosting websites. It stores all the necessary files and resources required to serve a website to users.

These files can include HTML documents, CSS stylesheets, JavaScript files, images, videos, and more. When a user accesses a website by entering its URL in their browser or clicking on a link, the web server retrieves the corresponding files and delivers them to the user’s browser.

Managing User Authentication and Authorization

Web servers play an essential role in managing user authentication and authorization. They can handle user logins, verify credentials provided by users against stored information (such as usernames and passwords), and grant or deny access to specific resources based on user permissions. This functionality allows websites to protect sensitive information and ensure that only authorized users can access certain areas or perform specific actions.

Logging and Monitoring

Web servers often have built-in logging capabilities that record various events and activities related to website traffic. These logs can include details such as IP addresses of visitors, accessed URLs, error messages, timestamps, and more. By analyzing these logs, administrators can gain insights into website usage, identify potential issues or security threats, and make informed decisions to improve the performance and security of the web server.

Load Balancing

In cases where a website receives high traffic or needs to handle a large number of concurrent users, multiple web servers can be used in a load balancing configuration. Load balancers distribute incoming requests across multiple servers to ensure efficient utilization of resources and prevent overload on any single server. This function helps improve website performance, scalability, and reliability.

Implementing Security Measures

Web servers play a crucial role in implementing various security measures to protect websites and users’ data. They can enforce SSL/TLS encryption to secure data transmission between the server and clients, prevent unauthorized access through firewalls and access control mechanisms, detect and mitigate DDoS (Distributed Denial of Service) attacks, and more. These security measures are essential for maintaining the integrity and confidentiality of sensitive information exchanged over the web.


A web server performs several functions that are vital for the proper functioning of websites. From handling HTTP requests and responses to hosting websites, managing user authentication and authorization, logging activities, load balancing, and implementing security measures – all these tasks contribute to delivering a seamless browsing experience to users while maintaining the integrity and security of web applications.
