What is my browser?

Your browser is:

CCBot/1.0 (+http://www.commoncrawl.org/bot.html)

HTTP_USER_AGENT returns a string describing the browser used to send the request.

Browser n. A program that accesses and displays files and other data available on the Internet and other networks.

The program that serves as your front end to the Web on the Internet. In order to view a site, you type its address (URL) into the browser's Location field; for example, www.webtechy.co.uk, and the home page of that site is downloaded to you. The home page is an index to other pages on that site that you can jump to by clicking an underlined hyperlink or an icon. Links on that site may take you to other related sites. Browsers have a bookmark feature that lets you store references to your favorite sites. Instead of having to type in the URL to visit the site again, you select the bookmark. Mosaic was the browser that put the Web on the map in 1993, but by the mid 1990s, Netscape Navigator (commonly known as "Netscape") had 80% of the market. Vying for top spot, Netscape and Microsoft's Internet Explorer (IE) constantly added new features and functions that fragmented Web sites into competing camps. Today, IE, which is included with every Windows PC, has more than 90% of the market. Netscape is still popular among devotees, and other browsers such as Opera have their followings.
