getting the full URL

[Daniel Blumenthal]

I'm trying to do what should be a fairly easy thing, but I'm really tearing
my hair out over this...
All I want is to be able to get the full URL (including scheme, queryString,
etc.).  Right now, I'm trying something like:
 
<%
out.write(request.getScheme() + ":/" +
request.getRequestURI().replace("jsp","do") +
(request.getQueryString().length() > 0 ? "?" + request.getQueryString() :
""));
%>
 
It feels like this should be a simple, single call. Any takers?
 
Thanks!
Daniel
