Get javascript version from browser !=IE in asp.net

Question

In my current logging class I log the browser, browser version and javascript version. The Javascript version I get through

HttpContext.Request.Browser.JScriptVersion

This works fine for IE, but not for any other browser. Is there another way (not javascript based) to detect the installed javascript version?

Answer 1

There's no standard for transmitting javascript version over HTTP, so unless a browser coincidentally conforms to IE's User-Agent header format, you won't be able to get that info
