A browser’s user agent string (UA) helps identify which browser is being used, what version, and on which operating system. When feature detection APIs are not available, use the UA to customize behavior or content to specific browser versions.
Like all other browsers,Chrome for Android sends this information in the User-AgentHTTP header every time it makes a request to any site.It’s also available in the client through JavaScript using thenavigator.userAgent call.

That’s where user agent switching enters the picture. Safari includes special features that make it possible to change the user agent. To activate the User Agent Switcher, in Safari, follow these steps:
1Click on the Gear shift icon, shown in the top right corner of the Safari web browser, to open the General Menu.
2Choose Preferences.
These are also shown in the figure from the last step.

If you don’t see the menu at the top of the Safari web browser, be sure to select the Show Menu Bar option from the general menu. When this option is selected, the name changes to Hide Menu Bar and the menu is visible at the top of the browser.
4Click the Develop menu option and select User Agent→<user agent>.
This opens a list of profiles.
5Open any web page to see how it displays with the selected profile.
In the figure the iPhone profile is selected and the Facebook web page displays in a narrow column aligned to the left — the version of the page that’s optimized for the iPhone. You see how to resize the browser window in combination with the user agent to create a general idea of how the page will display on an iPhone.
