How to detect browser settings?

[Chinh Tran Nam]

I got a strange requirement from my client to write a script (in Java, JSP, Javascript or whatever applicable for their JSP application) to check browser settings (IE) to see if it's configured as they need. Here are some settings it has to check:
- Browser version
- JVM version
- Cache Settings
- Font settings
- Security Settings: ActiveX control and plug-in?
- ...

and other system settings like Regional settings, Folder Options,...

Please let me know how to deal with this?
Thanks in advance.

To check the browser version, here is the function written is Javascript

function CheckBrowser()
{
// convert all characters to lowercase to simplify testing
var agt=navigator.userAgent.toLowerCase();
this.major = parseInt(navigator.appVersion);
this.minor = parseFloat(navigator.appVersion);
this.nav = ((agt.indexOf('mozilla')!=-1) && ((agt.indexOf('spoofer')==-1) && (agt.indexOf('compatible') == -1)));

if (this.nav)
{
BrowserType='NS';
}
this.ie = (agt.indexOf("msie") != -1);

if (this.ie)
{
BrowserType='IE';
}

if (agt.indexOf("netscape6")!=-1)
{
BrowserType='NS6';
}

get_os();

}

You can look at the request header information. You can read about that in the online book found at: Core Servlets and Java Server Pages

The other thing you can look at is system properties. There is alot of information stored in all those properties.
