	Shagul Khajamohideen	:	What is your setup like? Are you running Apache/Web Server in a separate machine?
	Mazhar Anwar	:	Dear Shagul, Back Url issue is there for local instance also. Simple way to reproduce it is remove VIEW Permission of one folder for Guest Users in Document Library Portlet. Now try to access that folder without login. You will get Error page showing message that "You do not have the required permissions." Now check the << Back URL on Right Tab. It seems some OOB Issue.
	Alfredo Larotonda	:	Shagul Khajamohideen: What is your setup like? Are you running Apache/Web Server in a separate machine? Yes, in my configuration I have an Apache Http Server in a separate machine that is connected via ajp with the Tomcat. But we used this kind of configuration with other releases of Liferay without any problem. Alfredo
