How to cite a website in LaTex

A. Using howpublished key of @MISC

Make an entry like following in bibtex file

@MISC{saharia08,
author = {N. Saharia},
title = {Use of how published key and website citation},
month = {December},
year = {2008},
howpublished=http://www.tezu.ernet.in/~utpal/nlp/}
}

Now in your latex document simply use \cite{--} command or \nocite{*} for printing all references

\documentclass{article}
\bibliographystyle{plain}
\usepackage{url}

\begin{document}
\nocite{*}
\bibliography{}

\end{document}
