Browser Detection

Does tapestry have a way to detect browser/version within component/page class?  Or by convention recommend some procedure?  To support logic <t:if test="${browserType.version}">rendering something</t:if>

Here is what I currently use (which may not be the best approach, but works
for my present needs).

UserAgent Service:

I primarily use it in this IEWarning component, which I have in my Layout:

Thanks.  Probably wrong question.  Best practice seems to be to detect capability supported in the user agent, not type, version etc.

I would @Inject Tapestry's Request

and
read it's headers. Just google on how to detect a specific browser. Since
