1. Basic knowledge:
User-Agent for Http Header
User Agent, also known as UA in Chinese, is a part of the HTTP protocol and is a component of the header domain. It is a special string header that provides information to the website about the type and version of the browser you are using, the operating system and version, the browser kernel, etc. Through this logo, the website visited by the user can display different layouts to provide users with a better experience or conduct information statistics. For example, accessing Google on a mobile phone is not the same as accessing a computer, which Google judges based on the UA of the visitor. UA can be camouflaged.
The standard format for the browser's UA string: Browser ID (operating system ID; encryption level identification; browser language) render engine identification version information. But browsers are different.
String description:
1. Browser logo
For compatibility and promotion purposes, many browsers have the same logo, so the browser logo does not indicate the true version of the browser, and the real version information can be found at the end of the UA string.
2. Operating system identification
3. Encryption level identification
N: Indicates no secure encryption
I: Indicates weak security encryption
U: Indicates strong security encryption
4. Browser language
The language specified in the preference > General > languages
5. Rendering engine
The main rendering engines used by the display browser are: Gecko, WebKit, KHTML, Presto, Trident, Tasman, etc., in the format of rendering engine/version information
6. Version information
Displays the real version information of the browser in the following format: browser/version information
Notes:
1. In the advertising targeting settings, browser targeting and operating system targeting are both targeting the information in the User-Agent.

2. Browser recognition
1. IE browser (take IE 9.0 as an example)
PC: User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0;
Mobile device: User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows Phone OS 7.5; Trident/5.0; IEMobile/9.0; HTC; Titan)
Since Aoyou, Window of the World, 360 Browser, Tencent Browser, Sogou Browser, Avant, and Green Browser all use IE kernels, the standard for IE browser judgment is the "MSIE" field, and the number after the MSIE field is the version number, but it also needs to be judged that it does not include "Maxthon", "The world", "360SE", "TencentTraveler", "SE", and "Avant" and other fields (Green Browser is not clearly identified). Mobile devices also need to determine the IEMobile+ version number.
2. 360 browser
PC: User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; InfoPath.2; . NET4.0C; . NET4.0E; .NET CLR 2.0.50727; 360SE)

Since Chrome and Nokia's Series 60 browser also use the WebKit kernel, the Safari browser must be judged to include the safari field and not the chrome and other information, and the number after "version/" is the version number. The one that includes the Mobile field under the above conditions is the Safari browser on the mobile device.
