Changes with nginx 0.4.4 02 Oct 2006

    *) Feature: the "scheme" variable.

    *) Feature: the "expires" directive supports the "max" parameter.

    *) Feature: the "include" directive supports the "*" mask.
       Thanks to Jonathan Dance.

    *) Bugfix: the "return" directive always overrode the "error_page"
       response code redirected by the "error_page" directive.

    *) Bugfix: a segmentation fault occurred if zero-length body was in PUT
       method.

    *) Bugfix: the redirect was changed incorrectly if the variables were
       used in the "proxy_redirect" directive.
