Guys I have this problem, in my document I insert normally the following command ans I got it in my text with huge spaces, It doesn't brake the url, what can I do?

Please clarify: do you use bibtex -- and, if so, which bibliography style file do you employ (plainnat maybe?) -- or biblatex? –  Mico Sep 6 '12 at 20:38
\bibliographystyle{unsrtnat} and I am using bibtex –  Vangelis Sep 6 '12 at 20:56

Try loading the url package with the option hyphens. Loading this package with this option will allow line breaks to occur after hyphens in the url string. A full MWE might be (assuming the .bib file is named test.bib) as follows:

\documentclass{article}
\usepackage{natbib}
\usepackage[hyphens]{url}
\bibliographystyle{unsrtnat}
\begin{document}
\nocite{*}
\bibliography{test} % assumes that bib file is named "test.bib"
\end{document}

yes the package url is loaded,I can see the URL the thing is that I have large spaces because it does not brake the url,due to Mico it is better but still the gap between URL and the address is too long,can I manage to fix by myself with \\,or something else,thank you very much –  Vangelis Sep 6 '12 at 22:40
@Vangelis - please consider amending your question to provide a full MWE -- if you want, you can take the example above as a starting point -- that shows the exact line width you're working with. Without that information it's going to be well-nigh impossible to give definitive (and satisfactory) advice. –  Mico Sep 7 '12 at 0:03
