Thanks for your reply.
You are right. I should clear the cookie from IE cache.
I am a getting a problem here. When the user clicks logout, the following
code executes.
<script type='text/javascript'>
function fdm_logout(){
alert(qx.io.local.CookieApi.get('jsessionid'));
qx.io.local.CookieApi.del('jsessionid');
window.location.href='logout.jsp';
}
</script>
I don't see 'jsessionid' in the cookie. How do I delete/access the cookie
using qooxdoo API. What are the cookies I should delete?
Thank you.
Kanugula.
