Topic awaiting preservation: safe code for cookies (Page 1 of 1)

I need a safe javascript code for setting, getting and deleting a cookie.
It must work fine in IE, Mozilla, Netscape and Opera, newer versions.
I have one that's not that safe.
Anyone knows of a free code that complies to such requirements?
Thanks.

Cookies are pretty old stuff, any code you get should be complient with everything since NS2, could be wrong ...
This is really something google/jsresource searchable.

The code I have is old, as the cookies, but it doesn't set the cookie in Opera.
Here's the code, that I found in Internet some years ago, I always used it, but now I found out it doesn't set cookies for Opera and I need it to:

function SetCookie (name, value)

	{ 

		var argv = SetCookie.arguments; 

		var argc = SetCookie.arguments.length; 

		var expires = (argc > 2) ? argv[2] : null; 

		var path    = (argc > 3) ? argv[3] : null; 

		var domain  = (argc > 4) ? argv[4] : null; 

		var secure  = (argc > 5) ? argv[5] : false; 

		document.cookie = name + "=" + escape (value) + 

			((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + 

			((path == null) ? "" : ("; path=" + path)) + 

			((domain == null) ? "" : ("; domain=" + domain)) + 

			((secure == true) ? "; secure" : ""); 

	}

Wow, I shouldn't have asked!
Actually, I found out why my stupid Opera browser (I just hate this browser) is not working fine with that SetCookie function.
Here's what I found in a Help page of Opera about cookies:
"Web developers should note that Opera does not store cookies sent from files loaded with the "file://" protocol, e.g. local files on your hard disk. The reason is that such cookies are considered a privacy risk"
Since I'm working locally, my addresses all start with file://
Damn Opera!

So I was right in the end ? yay

It depends on the context. It was perfectly correct but not related to the problem I was trying to solve...
I tested in my localhost and it worked fine. Hours lost because Opera is finicky.
