WebClientInfo throws exception when User-Agent is not set, but should it?

[Martijn Dashorst]

The following code is in WebClientInfo's constructor:

        public WebClientInfo(WebRequestCycle requestCycle)
        {
                super();
                HttpServletRequest httpServletRequest = 
requestCycle.getWebRequest()
                                .getHttpServletRequest();
                userAgent = httpServletRequest.getHeader("User-Agent");
                if (userAgent == null)
                {
                        throw new WicketRuntimeException("unable to read header 
'User-Agent'");
                }
                
properties.setProperty(ClientProperties.REMOTE_ADDRESS,httpServletRequest.getRemoteAddr());
                init();
        }

If I'm not mistaken, browsers can suppress headers, amongst which the
User-Agent. Shouldn't the WebClientInfo support this?
