Even though there can be multiple cookies with the same name on a single document, this most frequently occurs due to error rather than intention. I've never received a YUI bug report about this occurrence though I have considered returning an array of values instead of just the first value in this case. I might just go do that now. :)
My initial comment still remains: retrieving the value of a single named cookie seems to be a much more common use case than retrieving all cookies. You can choose to solve the duplicate cookie name issue in a number of ways, but not providing a way to access a cookie by name seems like a flaw in this design. Of course, if the main use case you're concerned about is retrieving all cookies, then feel free to disregard this feedback. -Nicholas ______________________________________________ Commander Lock: "Damnit Morpheus, not everyone believes what you believe!"

The problem is there can be multiple cookies with the same name for a given document. The YUI Cookie utility seems to assume there's only one. We could add a facility for filtering the results of getCookies, but that's easy enough to do correctly in JavaScript. Adam
