If you get the “Cookie Required” error when you running AGEE with XDS (that WI 5.0). This is because the change of cookies.js (Inetpub\wwwroot\Citrix\XenApp\app_data\clientscripts) in WI 5.0.
To get around this issue, open the cookies.js, you can find the line:
document.cookie = name + "=" + value + "; path=<%=wiContext.getWebAbstraction().getAbsoluteRequestDirectory()%>";
change it to the following and save the file:
document.cookie = name + "=" + value + ";
The problem will disappear. However, I am not sure if there is any adverse effect by doing this, so use this with care.
