Alignment problem with ieeetran website citation

Question

I am having difficulty getting properly aligned bibliography when citing a website (the url starts in the next line which causes huge horizontal gaps between words prior to the url).

Here is the screenshot from the "IEEEtran_bst_HOWTO.pdf":

Here is my output:

Note: The columnwidth is even wider in my code which should alleviate the problem.

My sample code is:

\documentclass[conference]{IEEEtran}

\def\BibTeX{{\rm B\kern-.05em{\sc i\kern-.025em b}\kern-.08em
    T\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}

\ifCLASSINFOpdf
\else
\fi

\hyphenation{op-tical net-works semi-conduc-tor}

\section{Introduction}

This demo file is intended to serve as a ``starter file''
for IEEE conference papers produced under \LaTeX\ using
IEEEtran.cls version 1.8b and later \cite{IEEEexample:bibtexFAQ}.

\bibliographystyle{IEEEtran}
\bibliography{ref}

\end{document}

And the bib file:

@electronic{IEEEexample:bibtexFAQ,
  author        = "David Hoadley and Michael Shell",
  title         = "{{\BibTeX}} Tips and {FAQ}",
  howpublished  = "{btxFAQ.pdf}",
  url           = "http://mirror.ctan.org/biblio/bibtex/contrib/doc/btxFAQ.pdf",
  month         = jan,
  year          = "2007"
}

Thank you in advance.

Answer 1

You can use the urlx package to add possible break points to the url:

\documentclass[conference]{IEEEtran}

\def\BibTeX{{\rm B\kern-.05em{\sc i\kern-.025em b}\kern-.08em
    T\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}

\ifCLASSINFOpdf
\else
\fi

\hyphenation{op-tical net-works semi-conduc-tor}

\usepackage{xurl}
