| browser sniffing
Browser sniffing describes the process
by which a Web site detects which versions of various browsers users are
running, in order to determine whether or not they can access certain Web
site features. Browser sniffing--usually accomplished with JavaScript--can
also be used to detect whether or not a user has a specific plug-in
required to access the site (such as Macromedia's Flash or RealNetworks'
RealPlayer). |
