Right now I open archives in my browser (localhost) with the follow line: :! start "http://localhost" file:///"%:p""<CR>.
It is possible to tell Vim: Open Firefox and hit refresh? (I don't want to refresh the current document I'm editing in Vim because if I open, for instance, the current CSS, the results won't show up in the browser.
PS: I'm using Windows XP (Unfortunately)
