Indeed I fault this was simply provided by the requuest since there
was getRequestURL in HttpServletRequest but it's reconstructed too
according to the javadoc. In that case yes we should probably
introduce a new API for it. But we need to be carefull with that in
the case where xredirect is using in another wiki but I don't think we
really have this usse case.

What about adding a api.XWiki#getRequestURL(boolean redirect) to
follow XWikiDocument#getURL ?

Other idea beiing to a simple api.XWiki#getRelativeRequestURL().
