Query version info from jsf application <p>I just stumbled upon a <a href="http://www.cigital.com/papers/download/dissecting_jsf_pt_aks_kr.pdf" rel="nofollow">paper</a> on JSF security containing the following statement:</p> <blockquote> <p>In Suns RI JSF implementation, the "com.sun.faces.disableVersionTracking" conguration parameter is defined explicitly. By default, it is set to false which means application running on the web server will throw the JSF version into the response headers when the web client queries for it</p> </blockquote> <p>But I don't understand how the web client is supposed to query for it? Is there a way to put extra (header) parameters to a request which makes JSF more chatty? I'm using MyFaces as the JSF implementation.</p>
