Document Classes ⇒ Any way to improve URL typesetting?

[l0calh05t]

Is there anyway to improve URL typesetting? (specifically in the bibliography) In the attached example, you'll see a lot of underfull hbox uglyness. Is there any way to solve this problem? (I'm using the url package with \def\UrlFont{\small\ttfamily})

The url package does a good job with URLs, or see hyperref with pdflatex. However, the "original" BibTeX styles do not include a URL field (too old): more modern ones do. What style are you using?

As I already said, I am using the url package (and also hyperref). For BibTeX I'm using the geralpha style.
