Syslog messages can be configured to use the server's local timezone

If one would like to see the syslog messages in the server's timezone instead of UTC it is now possible.

Added an option to enforce an enhanced password policy to local user directories

It is now possible to enforce users in local directories to use stronger passwords.

Number of all and displayed requests are shown in the ICAP history


Improved history loading and service starting time

History queries were updated so the ICAP service can start faster and loading the history also takes less time.


Content-Length header was missing from blocked responses

Content-Length header was not included in the block response making browsers to wait for more data and loading the page until it got timeout.

Fixed some minor issues on the default block page

Made some small fixes so the default block page is valid HTML5.
