How to identify "What's My User Agent" by using an online tool?Īs we discussed earlier, there is no standard way to write the user-agent string. The user-agent string usually helps in identifying the bots. For example, the webserver allows a particular bot to visit specific web pages, but it does not let another bot see any web pages. Web servers provide the bots unique treatments, require verifications, and give orders to various bots depending upon their programming by utilizing the robots.txt file. That data helps in gathering the market-share statistics of different browsers. User-agent helps in gathering the statistics on how the operating system and browsers are being used.For example, the mobile version of the website is slimmed and organized vertically for user easiness. User-agent helps in displaying the different contents to different operating systems.Sometimes, you might have seen this message "Open this with Internet Explorer." That is helpful because it serves the simple pages for the old browsers. User-agent helps in making different web pages available for various web browsers.To sum up, user agents are used for different purposes, and some of them are as follows.

It automatically sends the correct translation of certain documents based on the language preference of the user. Once the user-agent passes its ID card to the web server, it provides the files, media, and scripts suitable for the particular user.įiguring the user-agent string is not only helpful to us but also for the providers. That lets the website serve its various versions depending upon the user-agent string. Once a connection between a browser and web server is established, the content negotiation begins. Some browsers stuff the user-agent header with a lot of information.
However, there is no standard way to write the user-agent. User-agent is present in the HTTP headers when the browser wants to connect with the webserver.Įach bit of the user agent contains some detailed information. In simple words, it's a string of text that is unique for each software or browser on the internet and holds the technical information about your device and operating system. I bet you are now thinking, "what's my user agent?" It's an intermediary or middle man between you and the internet world. Generally, when the browser wants to connect with any website's server, it first sends the user-agent info to make the connection. Browsers are the internet's need, equipped with loads of security policies, server agreements, and connectivity codes to run ideally. Without a browser, we cannot surf the internet. From our mobile devices to our smart homes, we are always connected to the internet. But since the evaluation of the internet, now the browsers do that job automatically.Ĭurrently, there are more than 4.6 billion internet users in the world.
The user had to send the instructions to communicate. In the back days, the internet was on a manual system based on commands. The User-Agent Information identifies your browser and operating system and their versions. The tool displays the string text your web browser sends in the "User-Agent" header in the HTTP requests.
