Space between the two slashes in “http://” too big

Question

I'm using a lot of links with http:// in my document, but the two slashes are too much separated, I'd like them to be more near each other. How do I do this, in a neat way?

I'm using a sans-serif font: \renewcommand{\familydefault}{\sfdefault}

Answer 1

This should do what you want. Of course, you can choose the command name (\twobar) and the amount of kerning (–0.2em):

\documentclass{article}
\newcommand{\twobar}{/\kern-0.2em/}
\begin{document}
{\sffamily

http://www.jb.com.br

http:\twobar{}www.jb.com.br

}
\end{document}
