While browsing the file system.
Click on any file link to go to the page where the file contents are displayed, then when we click on 'Tail this file' link.
The control will go to the tail.jsp here when we
Click on 'Go Back to File View' option.
HTTP Error page not found will come.
This is because the referrer URL is encoded and the encoded URL is itself being used in the 'Go Back to File View' hyperlink which will be treated as a relative URL and thus the HTTP request will fail.
