A user agent is a computer program representing a person, for example, a browser in a Web context.
Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.
Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

Other sites, such as Vodafone Greece, are even worse by denying to load at all unless I open them in another browser such as Firefox. I want to use Internet Explorer 11 instead, so I tried to open the Developer settings and change the user agent in Firefox or Chrome, but apparently I did not do that correctly, all the affected sites still detect I run IE 11.
Have you tried using the string below -other examples are shown on the following page (you can even try the Linux version) Mozilla/5.0 (Windows NT 10.0; WOW64; RV:54.0) Gecko/20100101 Firefox/73.0 Other sites, such as Vodafone Greece, are even worse by denying to load at all unless I open them in another browser such as Firefox.
I want to use Internet Explorer 11 instead, so I tried to open the Developer settings and change the user agent in Firefox or Chrome, but apparently I did not do that correctly, all the affected sites still detect I run IE 11. User agent changes successfully but cannot trick Vodafone or YouTube.
Have you tried Microsoft Edge as the User Agent ? Try 'Other” at the bottom of the pop-up, enter the user agent string and “OK”.
I have searched the Web and find all sorts for Chrome etc but I cannot find a string to paste for IE of any version to run on Safari 13 I couldn't find Safari 13 specific IE user agent string either.
There was a IE extension that used to be free on chrome as well and now they want to charge u for it. I usually use the developer tab but my computer auto updated itself to 13.0.3 and not IE is gone ...
There has not been an InternetExplorer version for Mac in 16 years. There is no sergeant String that would Identify a current InternetExplorer version on a Mac.
This will work for the agent string: Mozilla/4.0 (compatible; MSI 8.0; Windows NT 5.1; Trident/4.0) Unfortunately, you have to do this step each time you want to use the in question website.
Mozilla/4.0 (compatible; MSI 8.0; Windows NT 5.1; Trident/4.0) Topics covered are: Installation, Deployment, Configuration, Security, Group Policy, Management questions.
If you are a consumer looking for answers or to raise a question, it's highly recommended you head on over to http://answers.microsoft.com/en-us 31 It turns out that the issues are related to efforts by our security team to mitigate the impact of the recently-discovered Pad (Web Proxy Auto-Discovery) protocol bug that puts Windows users at risk.
The quick-fix work-around is to uncheck all the boxes in the IE11 “local intranet” (see below) and used the “Advanced” feature to manually add in any websites that need to be viewed in compatibility mode: Your IT folks should now the settings of the browsers they support or how to diagnose and correct issues.
Neo win now reports that InternetExplorer11, as contained within the leaked build, identifies itself to host websites as Mozilla ... like Gecko.” Neo win speculates that the reason for this could be to start afresh: by confusing host websites with a new identifier, IE 11 might avoid having legacy CSS code thrown at it, dating back to the bad old days when web designers had to give InternetExplorer special treatment.
It's also been suggested that this could cause problems for business apps that genuinely rely on legacy CSS code -- although it's worth remembering that we're not looking at a final release here, and none of us (ahem) are even meant to be using it. They reveal a catalog of technical data about the device and software that the visitor is using.
Armed with this information, you can develop richer and more dynamic websites that deliver different experiences based on the user agent that's visiting. User agents are also critical in controlling search engine robots using the robots.txt file on your server.
But they don't function perfectly in every situation, and the information in an user agent string can be faked. In order to leverage this information, you need to understand the component parts of an user agent string and consider also the potential risks of using this method to deliver content.
When the internet was a text-based system, right back at the beginning of its use, users had to type commands to navigate and send messages. We simply point and click, and the browser is acting as our agent,” turning our actions into commands.
This is a really set of data for web developers since it allows them to customize the experience depending on the user agent that's loaded the page. Browsers are a straightforward example of an user agent, but other tools can act as agents.
Plus a whole range of feed readers, validators, cloud platforms, media players, email libraries, and scripts. Once the user agent has identified itself to the web server, a process called content negotiation can begin.
Note that a huge part of the user agent string is concerned with compatibility. That's because InternetExplorer originally had to declare itself to be Mozilla compatible in order to receive content with frames.
More, we can feed that data back into a cycle of continuous improvement, analytics and other processes, like conversion optimization. As we mentioned in the introduction, search engine crawlers are a very specific type of user agent.
An user agent is a particular string of characters in each browser that allows acts as an identification agent. The user agent string contains the user application or software, the operating system (and their versions), the web client, the web client's version, and the engine responsible for the content display (such as Apple WebKit).
