Your javascript has errors: nDays instead of ndays and variable VIH_HostName is not defined.
I changed the js code.
Try this:

XML

<script type="text/javascript">
        function setcookie() {
            var today = new Date();
            var expire = new Date();
            var ndays;
            if (ndays == null || ndays == 0) ndays = 1;
            expire.setTime(today.getTime() + 3600000 * 24 * ndays);
            document.cookie = "hostname=VIH_HostName;expires=" + expire.toGMTString();
        }</script>

and get the cookie from server side like this

Response.Write(Request.Cookies["hostname"].Value);

It works for me

Solution 1

there may be an issue with the name if you're setting a cookie using javascript and reading it with VB.net.

you could loop through the cookies collection of the request object and step through it using the debugger - see if you recognise your cookie at all.
