It adds a header line with a uuid for associating frontend and backend requests.

It fails without that module as well with this configuration:

nginx: nginx version: nginx/1.1.6
nginx: built by gcc 4.4.3 (Ubuntu 4.4.3-4ubuntu5)
nginx: TLS SNI support enabled
nginx: configure arguments: --conf-path=/etc/nginx
--prefix=/tmp/nginx-1.1.6 --with-http_ssl_module
--with-http_stub_status_module --with-debug
