Hi WWWers,
I want to tell NCSA Mosaic (or whatever browser) what it has to write
in the field "Document URL" (this would be a <HEADER>-Information).
Is there any tag to do this?
(the problem is, that I don't like the server-output from keyword-search
and such; e.g. instead of 
Document URL: http://httpserver.forwiss.uni-passau.de:2008/passau.map?245,189
I'd rather like to have 
Document URL: http://httpserver.forwiss.uni-passau.de/passau/stadt/plan/dom.html 
 - the last one, I would like to tell the parser explicitly)
