[xwiki-users] How to provide the backlinks if user land up on accessdenied page. Question :- How to provide the backlinks if user land up on accessdenied page.

I want to configure the accessdenied.vm( it is the page where i see the message You are not allowed to view this document or perform this action.). i want to provide the backlink on accessdenied.vm page which takes the user back to page where he is coming from. If it is not possible , even if backlink takes to home page of the space he is coming from will be fine.*Please provide me the inputs if it is configurable or with the small code snippet which i can iclude in accessdenied.vm* Intention of doing this is if user lands up on accessdenied page he has to go back by click on back button on browser but to make the application better i want the back link on accessdenied page itself . Thanks in advance.
