[root@web01 default]# cat web01/caffe/index.html 
rewrite ^/([0-9a-z]+)espressos/(.*)$ /web01/$1/$2 last;
[root@web01 default]# cat /app/server/nginx/conf/rewrite/default.conf

#if (!-e $request_filename) {rewrite ^/(.*)$ /index.php last;}
#if (!-e $request_filename) {return 404;}
#if ($http_user_agent ~ Firefox) {rewrite ^(.*)?$ /nginx-Firefox/$1 break;}
