The text on BrowserInfoPage should be customizable. Currently users gets a flash of the text on the page, and I'd rather they saw a blank page, or at least something that says "Loading..."
I realise that this is duplicate of the closed issue
WICKET-1591, but I have to say, I think you made the wrong call on that.
In order to change the text of the BrowserInfoPage, I have to override the WebRequestCycle.newClientInfo() method. My problem isn't that this is tricky, but implementing it requires copying a large chunk of code from the WebRequestCycle method, which could potentially change in future versions of the code, making my implementation prone to bugs.
In think that changing the text of BrowserInfoPage is probably a relatively common requirement, since it looks pretty unprofessional to have a flash of text before the first application page is displayed.
