Changes with nginx 0.7.27 15 Dec 2008v0.7.27

    *) Feature: the "try_files" directive.

    *) Feature: variables support in the "fastcgi_pass" directive.

    *) Feature: now the $geo variable may get an address from a
       variable.
       Thanks to Andrei Nigmatulin.

    *) Feature: now a location's modifier may be used without space before
       name.

    *) Feature: the $upstream_response_length variable.

    *) Bugfix: now a "add_header" directive does not add an empty value.

    *) Bugfix: if zero length static file was requested, then nginx just
       closed connection; the bug had appeared in 0.7.25.

    *) Bugfix: a MOVE method could not move file in non-existent directory.

    *) Bugfix: a segmentation fault occurred in worker process, if no one
       named location was defined in server, but some one was used in an
       error_page directive.
       Thanks to Sergey Bochenkov.
