Reading Cookie

[ravula2000]

A Cookie is written by using Javascript in an ASP Page.
Say the cookie is "ProductType"
When Iam trying to read it in aspx (asp.net page) Iam not getting nothing..

If Not Request.Cookies("ProductType&quot Is Nothing Then
pId = Request.Cookies("ProductType&quot.Value.ToString
end if

But when I create in the same aspx page I could able to read it in aspx as well as asp page..

Can some body explain me what is happening..

Thanks
