Detecting OS and Browser type?

Can any of you guys refer me to a script via VB or ASP that can detect the OS and Browser type a user is using?

Is it something similar like this IP addy code:
Your IP address is: <%=Request.ServerVariables("REMOTE_ADDR")%>

Thanks.

You could try here:

I've not written one in ASP, so I've not had to look for any references before. The example given would appear to cost $ though. The above sites home page has some good links to other ASP resources.

You can use javascript:

Browser = navigator.userAgent (ASP: Request.ServerVariables("HTTP_USER_AGENT") )
OS = navigator.oscpu


you can have also

navigator.appVersion
navigator.platform
navigator.appCodeName
navigator.appName
navigator.language
