There are so many tools and techniques to detect the client’s browser type. However, if you want a quick two-minute solution or you just want something simple, use this code to get the client browser:

 Dim mszBrowserTypemszBrowserType=Request.ServerVariables.Item("HTTP_USER_AGENT")Response.Write mszBrowserType

You may get output such as this:

 Mozilla/4.0 (compatible; MSIE 4.01; Windows 98) Mozilla/4.05 [en]C-AtHome0404 (Win95; U)

You can then parse the string for browser type or version number to see if it can support certain JavaScript or VBScript functions.
