redirecting a page base on cookie (cookie tutorial)

  1. J

    Hello,

    I've went over the code in the cookie tutorial on this site:

    /**
    * Read the JavaScript cookies tutorial at:
    * http://www.netspade.com/articles/javascript/cookies.xml
    */

    /**
    * Sets a Cookie with the given name and value.
    *
    * name Name of the cookie
    * value Value of the cookie
    * [expires] Expiration date of the cookie (default: end of current session)
    * [path] Path where the cookie is valid (default: path of calling document)
    * [domain] Domain where the cookie is valid
    * (default: domain of calling document)
    * [secure] Boolean value indicating if the cookie transmission requires a
    * secure transmission
    */
    function setCookie(name, value, expires, path, domain, secure)
    {
    document.cookie= name + "=" + escape(value) +
    ((expires) ? "; expires=" + expires.toGMTString() : "") +
    ((path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    ((secure) ? "; secure" : "");
    }

    /**
    * Gets the value of the specified cookie.
    *
    * name Name of the desired cookie.
    *
    * Returns a string containing value of specified cookie,
    * or null if cookie does not exist.
    */
    function getCookie(name)
    {
    var dc = document.cookie;
    var prefix = name + "=";
    var begin = dc.indexOf("; " + prefix);
    if (begin == -1)
    {
    begin = dc.indexOf(prefix);
    if (begin != 0) return null;
    }
    else
    {
    begin += 2;
    }
    var end = document.cookie.indexOf(";", begin);
    if (end == -1)
    {
    end = dc.length;
    }
    return unescape(dc.substring(begin + prefix.length, end));
    }

    /**
    * Deletes the specified cookie.
    *
    * name name of the cookie
    * [path] path of the cookie (must be same as path used to create cookie)
    * [domain] domain of the cookie (must be same as domain used to create cookie)
    */
    function deleteCookie(name, path, domain)
    {
    if (getCookie(name))
    {
    document.cookie = name + "=" +
    ((path) ? "; path=" + path : "") +
    ((domain) ? "; domain=" + domain : "") +
    "; expires=Thu, 01-Jan-70 00:00:01 GMT";
    }
    }

    I was wondering how to redirect to a specific page based on the cookie. I believe I would have to create a seperate function to redirect to the page based on the cookie value...

    Thanks for any help you can lend.
