That is, you can evaluate the headers, from where the request came from, which protocol was used, what MIME types are accepted and so on. Still, you can't get details about the client configuration beyond what you can tell from that information. Additional information may be available via JavaScript, and BrowserHawk itself seems to make extended use of it. Just to note, when testing the link given the information proved to be not too reliable. Most tests (Konqueror 3.1, SuSE Linux 9.0, Sun Java 1.4.2, Applets accepted, JavaScript enabled, Acrobat Reader 5 installed; I have a P4, 512MB of RAM and hdb has 120GB, 77% free) failed with my current setup. Still, none of the latter got detected. Therefore, I wouldn't rely on BrowserHawk or the like. Note: the fact it correctly detected Konqueror 3.1 is due to the circumstance I didn't tell it to cloak as Explorer, whatever version desired, and you can do the same with Opera on Windows too, at least. Then, if your app really depends on such info, I guess you're on the wrong track somewhere. For web applications, all this extra info is not needed, so you can't rely on anything except what the headers tell you. In a JSP browser snoop page, you're limited to exactly the same. There already is such a page in the standard Servlet demos, and getting any information beyond that is a really hard job, I guess. Mind: snooping the concrete user's system configuration was not part of the deal when they invented HTTP.
