Prohibiting line break at specific point of url while using \url command

Question

I have a \url{some.edu/page} that breaks just before .edu I would like to have it break at the / at worst, or not at all. How can I do that?

Answer 1

The characters, where breaks are allowed, can be changed. See documentation of package url, section "5.2 Changing linebreaks". In this case the dot is part of \UrlBreaks. The following redefines it without the dot:

\usepackage{url}
\renewcommand*{\UrlBreaks}{\do\@\do\\\do\/\do\!\do\_\do\|\do\;\do\>\do\]%
  \do\)\do\,\do\?\do\'\do+\do\=\do\#}%
