Re: Web Browser detection in JSP
I check for MSIE instead of 'compatible' because I thought browsers like Opera
might also have compatible in the string. Here are the strings I get returned on
two systems (NT and Win 95)
I get this returned for Netscape:
Mozilla/4.73 [en] (WinNT; U)
Mozilla/4.08 [en] (Win95; I;Nav)
and this for Internet Explorer:
Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)
Mozilla/4.0 (compatible; MSIE 4.01; Windows 95)
I would be interested in learning what some of the less common browsers are
returning...
Donald
This is the JSP I used:
html
headtitleBrowser Test/title/head
body
p%= request.getHeader("User-Agent") %/p
/body
/html

Information like "what JavaScript version this client supports" is known by BrowserHawk through the use of a browser data file that can be updated regularly for new browsers. They have a full list of properties on their site. Features like if Java is on or off does require the tool does some interaction with the client. But I wouldn't call it "dumb"! If you need to know whether Java is on or off, you can't know by sniffing headers. They've sold this BrowserHawk tool in the ASP market for years. They're now interested in supporting servlets/JSP.
