[Javascript] Naming cookies

[javascript@xxxxxxxxxx (Steve Hearne)]

Can you tell me if it is possible to save cookies (using JavaScript) under =
a particular name, or do they have to use the site/page name they are =
called from?  Hmmm... by this i mean the text file which contains the =
cookies for a particualr site (do i have that right?)

I have spent the last hour trying to locate this info. and found out a lot =
of stuff and some excellent recipies but not this info.

Cookies on my machine always seem to be saved in the following format;

username@site[n]

How do they get the username? (mine is my Novel login).  If i could grab =
this directly, i would be a happy man. Well, happier.  What about the =
number in brackets - what is that that all about?

Thanks.
Steve
