nginx 1.3.3
*) Feature: entity tags support and the "etag" directive.
*) Bugfix: trailing dot in a source value was not ignored if the "map"
directive was used with the "hostnames" parameter.
*) Bugfix: incorrect location might be used to process a request if a
URI was changed via a "rewrite" directive before an internal redirect
to a named location.
