browser version detection from server side with java

Question

I saw many posts related to the browser detection, User agent detection etc...I want to detect the version from server side and send appropriate data based on that.

Answer 1

Here is the code explaining how to do it using user-agent-utils:

String userAgent = req.getHeader("user-agent");
UserAgent ua = UserAgent.parseUserAgentString(userAgent);
Version browserVersion = ua.getBrowserVersion();
String browserName = ua.getBrowser().toString();
int majVersion = Integer.parseInt(browserVersion.getMajorVersion());
