nginx-0.3.56-RELEASE importrelease-0.3.56

    *) Feature: the "dav_access" directive.

    *) Feature: the "if" directive supports the "-d", "!-d", "-e", "!-e",
       "-x", and "!-x" operators.

    *) Bugfix: a segmentation fault occurred if a request returned a
       redirect and some sent to client header lines were logged in the
       access log.
