Long URL in Bibliography section exceeds the bounds of the page

I have an external bib where I put a reference to an external URL.

@misc{myreference,
author = {The Author},
title = {The Title},
howpublished = "\url{http://thisismyurl/2010/3/a-long-url-here}",
year = {year}
}


When I compile, the URL (when displayed in Bibliography) exceeds the bounds of the page (set as customs). The URL is composed by different terms concatenated with - symbol. a-long-url-here can be the following:

abc-abc-abca-abc-ab-abc-abc-abc-a-abcabc-ab-abc-abc/


The bib is inserted in the following manner:

\bibliographystyle{IEEEbib}
\bibliography{bibliog}


Is there any mechanism to fix this behaviour? I checked perform a line break of an URL in bibliography manually (biblatex, hyperref) but I don't know how to use it in my situation.

Edit

For the sake of completeness, I use PdfLatex.

Did you try the suggested \sloppy and \emergencystretch settings? –  mafp Dec 28 '12 at 18:47
@mafp No. Where do I have to put these commands? Thanks. –  flexaddicted Dec 28 '12 at 18:52
since the url package allows breaks, it sounds like you are using hyperref, which doesn't allow them by default. if you specify the option \usepackage[breaklinks]{hyperref} you should get better results. of course, this is just a guess; i'm not familiar with the IEEEbib style, so it may apply some restrictions i'm not aware of. –  barbara beeton Dec 28 '12 at 18:58
To avoid the option clash, you can type \hypersetup{breaklinks=true}. –  Mico Dec 28 '12 at 20:51
Don't provide both of these instructions, but only the first one -- after the hyperref package has been loaded either directly by one of your own instructions or indirectly by one of the packages you load (or by the document class). –  Mico Dec 30 '12 at 0:15

Assuming that you have a file named bibliog.bib with the contents given in your posting, the following MWE (minimum working example) generates a reference with the URL string broken at a hyphen. The key steps are (i) load the url package with the hyphens option and (ii) enable the breaklinks=true option of the hyperref package.

\documentclass{article}
\usepackage[hyphens]{url}
\usepackage{hyperref}
