    internal;
    proxy_pass http://test_backend$request_uri;
}

1.13.4 更新内容：

• Feature: the ngx_http_mirror_module.

• Bugfix: client connections might be dropped during configuration testing when using the "reuseport" parameter of the "listen" directive on Linux.

• Bugfix: request body might not be available in subrequests if it was saved to a file and proxying was used.

• Bugfix: cleaning cache based on the "max_size" parameter did not work on Windows.

• Bugfix: any shared memory allocation required 4096 bytes on Windows.

• Bugfix: nginx worker might be terminated abnormally when using the "zone" directive inside the "upstream" block on Windows.
