Citing websites on BibTeX

While writing the last paper I'm working on, I realised I also needed to cite some web reference. As I'm used to input BibTeX entries that are papers or books, I didn't really know how to cite websites.
Apparently this is not supported by BibTeX, which is strange since the web is growing more and more important nowadays, so I found out another way to cite the online resources. This is not really the correct way to do it, as it hasn't been figured out yet, and some trick were using the @MISC type. I will use the @ONLINE type:

@ONLINE{Caio:2013:Online,
author = {Caio, Tizio},
title = {Tizio Caio Website of important reference},
month = mar,
year = {2013},
url = {http://www.tiziocaio.org/ref/}
}

Some other way to turn this around include @MISC (as mentioned before), @OTHER, and @BOOKLET. The code is basically the same, and so is the result eventually:

@MISC{Caio:2013:Misc,
author = {Caio, Tizio},
title = {Tizio Caio Website of important reference},
month = mar,
year = {2013},
url = {http://www.tiziocaio.org/ref/}

@OTHER{Caio:2013:Other,
author = {Caio, Tizio},
title = {Tizio Caio Website of important reference},
month = mar,
year = {2013},
url = {http://www.tiziocaio.org/ref/}

@BOOKLET{Caio:2013:Booklet,
author = {Caio, Tizio},
title = {Tizio Caio Website of important reference},
month = mar,
year = {2013},
url = {http://www.tiziocaio.org/ref/}
}

I hope this is going to be of some kind of help, while waiting for some standard way to do it.
