I have nginx setup to serve from /usr/share/nginx/html, and it does this fine. I also want to add it to serve from /home/user/public_html/map on the same domain. So:

my.domain.com would get you the files in /usr/share/nginx/html
my.domain.com/map would get you the files in /home/user/public_html/map

With the below configuration (/etc/nginx/nginx.conf) it appears to be going to my.domain.com/map/map as noticed by this:

2011/03/12 09:50:26 [error] 2626#0: *254 "/home/user/public_html/map/map/index.html" is forbidden (13: Permission denied), client: <edited ip address>, server: _, request: "GET /map/ HTTP/1.1", host: "<edited>"

I've tried a few things but I'm still not able to get it to cooperate, so any help would be greatly appreciated.
