User Agent Information
In the old days, the internet was a manual command-based system. The user had to send the instructions to communicate. But since the evaluation of the internet, today the browsers do the task automatically.
There are more than 4.6 billion internet users globally, and we are always linked to the internet.
Without a browser, we cannot surf the internet. Browsers are the internet's need. They are loaded with security policies, server agreements, and connectivity codes to run ideally.
Generally, when the browser wishes to connect with any website's server, it transmits the user-agent info to connect.
What is My User Agent?
I bet you are now thinking, "What is my user agent?" It's an intermediary or middleman between you and the internet world. Simply explained, it's a string of text unique for each software or browser on the internet and holds the technical information about your device and operating system.
User-agent is contained in the HTTP headers when the browser wishes to connect with the web server.
Each byte of the user agent contains some detailed information. However, there is no standard way to write the user agent. It differs from browser to browser. Some browsers clutter the user-agent header with a lot of information.
Once a browser and web server connection is established, content negotiation begins. That allows the website to offer its numerous versions based upon the user-agent string. Once the user-agent passes its ID card to the web server, it gives the files, media, and scripts suitable for the particular user.
The user-agent string is not only valuable to us but also to the suppliers. It automatically transmits the correct translation of some documents based on the user's language preference. You may have encountered this when accessing websites with a different language that is automatically translated.
Uses of User-Agent
To sum up, user-agent is utilized for different purposes, some of which are as follows:
- User-agent aids in making different web pages available for various web browsers. That is helpful because it offers simple pages for the ancient browsers. Sometimes, you might have encountered this message: "Open this with Internet Explorer."
- User-agent aids in displaying the varied contents to different operating systems. For example, the mobile version of the website is reduced and organized vertically for user ease.
- User-agent helps gather the statistics on how the operating system and browsers are utilized. That data assists in compiling the market-share statistics of different browsers.
- Web crawlers also employ user agents. Web servers provide unique bot treatments, need verifications, and send directions to diverse bots depending upon their programming by employing the robots.txt file.
- For example, the web server permits a particular bot to see specific web pages but does not let another bot see any web pages. The user-agent string typically assists in identifying the bots.
Can I Alter or Spoof My User Agent?
Yes, you may change your user agent, and that procedure is called user-agent spoofing. Sometimes, we need to test different things.
For example, you are running a campaign for macOS, and you want to figure out whether the campaign is operating appropriately for macOS and not targeting Linux users; altering the browser's user agent assists you in this regard.
Web developers usually regularly change the user agent to check the progress of their website's functioning in different browsers and devices.
For switching 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 transmit with its HTTP requests.
