What Is My User Agent

How do I find out my user agent?

My User Agent Your user agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36 Operating System & Version Windows 7 Browser & Version Chrome 41.0.2228 User agents are used throughout client-server computing and application user agents that request web-based content are commonly browsers and search engine bots.

  1. Newsreaders, screen readers and other web-related applications and systems act as agents as well.
  2. In the case of a user requesting a web page with a browser, the browser transmits details about the user’s computer operating system as well as information about the browser itself.
  3. The user agent information is contained in the header portion of the request.

The receiving server may choose to ignore the information in the user agent, or modify its response based on the information. Web site developers frequently leverage information parsed from user agents to optimize the user experience based on the browser and device types.

With the recent explosion of smartphones, many developers now check the device type and direct the user to a site optimized for mobile or use a mobile optimized style sheet. Some web sites check the browser version in the user agent to ensure the user has a current browser and directs them to various vendors’ web sites to download a newer version.

Many enterprise applications check browser type and versions due mostly to heavy customization of the UI and to ensure an optimal experience. The user is typically denied access without the application’s “certified” browser or is notified the experience will be less than optimal.

Mozilla/5.0 – Historical leftover from when new browsers entering the market spoofed their user agents; ignore it.

What is my user agent headers?

HTTP headers | User-Agent The HTTP headers User-Agent is a request header that allows a characteristic string that allows network protocol peers to identify the Operating System and Browser of the web-server. Your browser sends the user agent to every website you connect to.

  • There is no conventional way of writing a user agent string as different browsers use different formats and many web browsers load a lot of information onto their user agents.When your browser is connected to a website, a User-Agent field is included in the HTTP header.
  • The data of the header field varies from browser to browser.

This information is used to serve different websites to different web browsers and different operating systems. Syntax: User-Agent: / or User-Agent: Mozilla/ ( ) ( ) Directives There are three directives in HTTP headers user-agent.

product: This holds the product identity. product-version: This holds the product version of the used product. comment: This holds the sub-product information of the used product

You can also check your User-agent with the help of, Example: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36 The following conclusions can be drawn with the help of user-agent header:

The user agent application is Mozilla version 5.0.The operating system is NT version 10.0 (and is running on a Windows(64-bit) Machine).The engine responsible for displaying content on this device is AppleWebKit version 537.36 (KHTML, an open-source layout engine, is present too).The client is Chrome version 77.0.3865.90.The client is based on Safari version 537.36.

User-Agent Switcher Simplest way to switch between user-agents in your browser! User Agent Switcher is simple, but powerful extension. And much easier to use the Internet, regardless of which browser or operating system you prefer. It adds a toolbar button that you can use to toggle between different commonly used user agent strings.

So what’s a User Agent? A user agent is a small text description of your device that is sent with every web request. Websites can detect the browser you’re using and serve different content – this is why iPhone and Android users see special mobile websites when they browse the web. With this chrome extension, you can quickly and easily switch between user-agent strings.

Also, you can set up specific URLs that you want to spoof every time. Changing User-Agent allows you to mimic, spoof or fake other browsers, devices or search engine spiders. Note: Sometimes problems may occur after using a mobile user-agent, and won’t switch back no matter what you spoof, you will need to switch the user-agent back to Chrome and clear your cookies for the sites to treat the browser normally again! : User-Agent Switcher

Is the user agent string considered personal data? A user agent string may be personal data depending on how it is processed. Aggregate statistics of user agent strings are not personal data. But if you combine user agent records with IP addresses or other identifiers, the user agent string would relate to a data subject that you can single out/identify.

  • While user agent strings can contain arbitrary text (someone could override their user agent to put their name, street address, and tax ID there), this does not seem to be particularly relevant.
  • For GDPR compliance, it matters more how you process the data.
  • While GDPR is a foundational data privacy law in the EU, the ePrivacy directive goes into more detail for internet and telecommunication services.

A user agent string would usually fall under it’s definition of “traffic data” because it’s generally transmitted as a HTTP header. Per ePrivacy Art 6, traffic data can only be processed:

for transmitting a communication, e.g. to have your web server respond with different content depending on mobile or desktop user agents; when the data is made anonymous, e.g. as part of aggregate statistics on browser versions; for billing purposes; or when the user consents, where “consent” is defined by the GDPR.

However, the ePrivacy directive is not immediately applicable law, and every EU member state has its own law implementing this directive. Thus, you should look at the laws in the country in which you reside. These laws do not override GDPR but augment it, so you still have to ensure GDPR compliance (such as having a legal basis per GDPR Art 6 for every processing of such data).

  • I think that recording tuples for the purpose of building statistics is not personal data in your context, or is at least a processing of personal data that doesn’t require identification per GDPR Art 11.
  • Such records would likely count as “anonymous” in the sense of ePrivacy, so that you can collect such statistics without having to ask for consent.

However, if a user agent is rare relative to the traffic volume on your site, it would still be possible to single out a particular user. Thus, it could make sense to break the connections between date and user agent or to never store individual records, just aggregate data.

using streaming Bloom filters to avoid storing unique records, or using other privacy-preserving probabilistic data structures only storing denormalized records, and truncating/rounding timestamps to avoid linking events via their time. Instead of one table with a per event you might have separate tables with and aggregate records were the time slots are appropriately spaced for the traffic of the site.

What is Windows user agent?

In this article – The User Agent String contains information about a browser’s identity. The User Agent String is reported to the web server as an HTTP header every time that a browser makes a request to a web server. You can also access it through a client-side script. Typically, the User Agent String is parsed specifically for the MSIE substring. Based on the reported version of the browser, the client-side or server-side programming logic takes a different action. For more information about the User Agent String, see What Will Windows Internet Explorer Report as the User-Agent String? in the MSDN Library.

Is user agent the same as browser?

Introduction in Guidelines – revisions and additions to http://www.w3.org/WAI/UA/2011/ED-UAAG20-20110525/#introduction A user agent is any software that retrieves and presents Web content for end users or is implemented using Web technologies. User agents include Web browsers, media players, and plug-ins that help in retrieving, rendering and interacting with Web content.

  • The family of user agents also includes operating system shells, consumer electronics with Web-widgets, and stand-alone applications or embedded applications whose user interface is implemented as a combination of Web technologies.
  • Comment: greg – I suggest having at least a user-friendly paragraph in the intro that explicitly refers readers to the glossary for a formal, normative definition.

While rendering engines and other technologies used to build user agents are not by themselves considered user agents, it is fundamental to user agent accessibility that these technologies support user agent requirements. In building a user agent the developer should fully understand the support for UAAG 2.0 when selecting technologies.

Why is user agent spoofing useful? – For web developers, adjusting the UA string can help to check the compatibility of websites on different devices and browsers. In fact, many will employ a user agent spoofing Chrome extension or plugin to help them adjust their UAS on the fly – a popular method of testing websites or browser compatibility.

Some marketers may also use user agent spoofing to see how their ads, for example, display campaigns, are showing on different browsers. This can help them troubleshoot display issues or simply see how the images look on a browser that they wouldn’t otherwise have access to. So user agent spoofing isn’t always a malicious practice.

But, as you might already be able to see, it can easily be used by fraudulent parties. In fact, in theory, a spoofed UA string shouldn’t need to be used out in the wilds of the internet.

Unpacking the User-Agent string – The information contained within a User-Agent HTTP request header is also known as the User-Agent (UA) string. This string contains information on the device. For example, if you browse the web on your smartphone, your device will send a HTTP request header to the web server, saying that it is a mobile device.

The website will then respond and show you the mobile version of the page. We could just give you a list of User-Agent strings and be done with it. But that’s not particularly good for developing your learning, is it? Instead, let’s dissect some example User-Agent strings: Mozilla/5.0 (Linux; Android 12; Pixel 6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.62 Mobile Safari/537.36 Mozilla/5.0 appears at the start of most UA strings.

It can largely be ignored as it has no relevance to the associated device. Historically, it was used to indicate compatibility with the Mozilla rendering engine, a piece of software that draws text and images on the screen. Linux; Android 12 tells us details about the operating system.

In this case, the device is running the Android operating system, which is based on Linux. For mobile User-Agent strings, the Pixel 6 section of the string tells us the device name or device model number. In this case, this User-Agent came from a Google Pixel 6 phone. In other instances (such as for a Windows desktop device), this element of the string may define the device architecture.

AppleWebKit/537.36 indicates what browser rendering engine is used. A rendering engine is what transforms HTML into an interactive webpage on the user’s screen. The WebKit browser engine was developed by Apple and is primarily used by Safari, Chromium, and all other WebKit-based browsers.

(KHTML, like Gecko), This section of the string doesn’t necessarily provide more detail on the device but ensures compatibility for historical reasons. Check out the history of the User Agent string guide from Human Who Codes for more details. And finally, Chrome/93.0.4577.62 Mobile Safari/537.36 has more detail on the browser and its version number.

In this example, the device is using a mobile version of Chrome, version 93. So, the different sections of this Chrome User-Agent string are: Mozilla/5.0 (Linux; Android 12; Pixel 6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.62 Mobile Safari/537.36 Let’s look at another example, this time it’s a Firefox User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0 Firefox User Agent strings tend to follow a four-component format, whereas Chrome User Agent strings may include more elements.
