How Web Servers work
Web servers are the computers, which host the websites and other web content over the Internet. Whenever we type in the URL of a particular website, it gets translated to an IP address and gets directed towards the web server which hosts the website whose name we have typed in. Therefore, in a sense we request the web server to display the pages it is hosting to be displayed on our browser.
After receiving the request, the server sends the HTML text which is arranged on screen in form of the web page. Other content apart from HTML documents include images, style sheets and JavaScript etc.
Hypothetically we say web servers are online twenty four hours a day and three sixty five days a year. Websites which receive heavy traffic employ the use of powerful and fast servers because there are usual occurrences of server breakdown in case of heavy load of traffic. Whenever as a user we come across a website which takes more than usual display time of web pages on our browser it means the server actually is quite slow in responding to the client’s or user’s request.
Common features of the web servers are
- Server Side Scripting – In this as a user requests a web page it is fulfilled by web server by executing a script directly on the web server. Usually the scripts are run on the client’s side but server side scripting is used to display more dynamic and interactive pages.
- Bandwidth Throttling – This technique is used by servers which handle large traffic to decongest and manage the network. This done by limiting the number of requests to which the server replies.
- Virtual Hosting – Virtual hosting is a technique where, more than one domain names are registered on a single IP address. This technique enables single machine to share resources like memory and processing time.
