[icon] http://www.server.tld
Of course, it should be vector based ;-)
Shouldn't be hard to make something like (untested):
\newcommand{\urlicon}{\includegraphics{iconfile.eps}~\url}
If you're using pdflatex, you can use bitmapped formats as well, like
.jpg or .png.
A different approach might be (also untested):
\renewcommand{\UrlLeft}{\includegraphics{iconfile.eps}~}

I'm sorry: rereading your quesion, I see you're asking if "is there a
provided icon", not "how to get it". AFAIK, the answer is "no".
