javascript e asp

[Maxb]

I don't understund this script (i'm italian and speek english not very well)

<script language="javas cript">
var browser='';
browser=navigat or.appName;
document.cookie = "ScreenSize =" + screen.width + "-" + screen.height;
document.cookie = "Browser=" + browser;
</script>
<%
response.write( Request.Cookies )
%>
The cookie is write at first time but with the asp script i can read only
after one refresh.
Someone has the solution?

There is nothing wrong here, Max, so there is no solution.

ASP runs on the server BEVORE the page gets to the browser,
so the refresh is necessary to read the cookie.

I think the answer is that you are looking at the properties of the
Request object, but on the first page request there are no cookies.

When a page is requested by the browser, it sends to the server all
the cookies it holds that are associated with that page. Those
cookies will be then viewable as a property of the Request Object in
ASP. But on the first request for the page, those cookies will not be
in the browser's cookie jar; thus, nothing will be sent, and so that
property of the Request Object will be empty. When you "refresh," the
cookies are available and are sent as part of the page request. They
now are viewable through the Request Object.
