User agent information

In days gone by, the Internet was a manual command-based system. The user had to send the instructions to communicate. But since the Internet assessment, browsers now do that job automatically.

There are more than 4.6 billion Internet users worldwide, and we are always connected to the Internet.

Without a browser, we cannot browse the Internet. Browsers are the necessity of the Internet. They are equipped with security policies, server agreements, and connectivity codes to function ideally. Generally, when the browser wants to connect to the server of any website, it sends the user agent information to connect.

What is my user agent?

I bet you’re now thinking, “what’s my user agent?” It is an intermediary or intermediary between you and the Internet world. Simply put, it is a unique text string for each software or browser on the Internet and contains the technical information about your device and operating system. User-agent is present in the HTTP headers when the browser wants to connect to the web server.

Each bit of the user agent contains detailed information. However, there is no standard way to write the user agent. It varies from browser to browser. Some browsers populate the user-agent header with a lot of information.

Once a connection is established between the browser and the web server, the negotiation of the content begins. That allows the website to serve its various versions depending on the user-agent string. Once the user agent passes your ID card to the web server, it provides the appropriate files, media, and scripts for the particular user.

The user agent string is not only useful for us, but also for suppliers. It automatically sends the correct translation of certain documents according to the user’s language preference. You may have seen this when accessing websites with a different language that is automatically translated.

In short, user-agent is used for different purposes, some of which are as follows.

  • User-agent helps to make different web pages available for various web browsers. That’s useful because it serves simple pages for older browsers. Sometimes, you may have seen this message; “Open this with Internet Explorer.”
  • User-agent helps to display the different contents to different operating systems. For example, the mobile version of the website is slimmed down and organized vertically to make it easier for the user.
  • User-agent helps collect statistics on how the operating system and browsers are used. That data helps collect the market share statistics of different browsers.
  • Web crawlers also use user agents. Web servers provide unique bot treatments, require verifications, and give commands to various bots depending on their programming; using the TXT file. For example, the web server allows a particular bot to visit specific web pages, but does not allow another bot to view any web pages. The user-agent string usually helps identify bots.

user agent?

For example, you are running a campaign for MAC OS and want to find out if the campaign is running correctly for MAC OS and is not targeting Linux users; Changing the browser user agent helps you in this regard.

Web developers typically change the user agent daily to check the progress of their website’s behavior across different browsers and devices.

To change the user agent,

you can rely on a browser extension or use the developer console to manually change the user agent that your browser will send with your HTTP requests.
