cookies set in .Net read clientside in Firefox but not IE or Safari

The following .Net settings set the cookie 

                HttpCookie c = new HttpCookie("tw"); 
                c.Expires = DateTime.Now.AddDays(100);
                c.Path = "/"; 
                c.Secure = false;  
                c.HttpOnly = false;

The following javascript reads the cookies 

    function getCookie(c_name)
    {
    var i,x,y,ARRcookies=document.cookie.split(";");
    for (i=0;i<ARRcookies.length;i++)
    {
      x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
      y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
      x=x.replace(/^\s+|\s+$/g,"");
      if (x==c_name)
        {
        return unescape(y);
        }
      } 
}

No extra headers are sent in the request. This works in Firefox but not IE or Safari

What happens here is that you don't set value to your cookie. In IE, valueless cookie doesn't contain '='. This means, that in your code x is "" and y is "tw". Then, in the if clause, the name comparison always fail, because x is an empty string. As a result, the function returns undefinied. Rewrite your logic in a way that handles the absence of '=' in a valueless cookie in IE.
