ngx_http_mirror_module - Module ngx_http_mirror_module




=head1



The C<ngx_http_mirror_module> module (1.13.4) implements
mirroring of an original request
by creating background mirror subrequests.
Responses to mirror subrequests are ignored.

        mirror /mirror;
        proxy_pass http://backend;
    }
    
    location = /mirror {
        internal;
        proxy_pass http://test_backend$request_uri;
    }

L<ngx_http_proxy_module>,
L<ngx_http_fastcgi_module>,
L<ngx_http_scgi_module>,
and
L<ngx_http_uwsgi_module>
