File access via haproxy

[Andrey Zakabluk]

Hi! Can I redirect request from client on the local directory(server) via 
haproxy? For example:
If user send request - crossdomain.xm I am redirect its on the directory  
/opt/crossdomain/ , folder for files. This is file be on the server whith 
haproxy.

In NGINX this is has form

  location / {
             root /opt/nginx/www/; # folder for store files
             index  crossdomain.xml;

Merci!
