/* Use this function to see if Cookies are enabled.
 * Use this in the body onload event and use a hidden field on the main page.
 *
 * We are trying to detect if both Javascript and Cookies are enabled.
 * This is done by using Javascript to set a cookie and then checking it.
 * If Javascript is enabled then we can check if cookies are enabled.
 * If Javascript is not enabled then we will be able to check if cookes are enabled, but 
 * that's ok since both need to be enabled.
 *
 * This code is taken from http://www.aspfaqs.com/webtech/082400-1.shtml
 *
 * We also set the focus on the login input box as a side benefit.
