Hello itpp,i have been abled to use ngx_http_geo_module. Now the request
coming from local ISP will first go to the main server (US) and then main
server will check if the ip is 1.2.3.4 so it'll direct the request to the
local caching server and than caching server will check if the file is
cached or it should again get the file from main server and cache it
locally.

When i tested it locally, it worked fine but the file URL in firebug is
coming from MAIN server when it should have come from the local caching
server. I can also see the caching directory size increases when the
matching client via geo module is directed to the local caching server but
the URL remains the same in firebug.

US config :-

geo $TW {
default 0;
192.168.1.0/24 1;
}



server {
listen 80;
server_name 002.files.com;
# limit_rate 600k;
location / {
root /var/www/html/files;
index index.html index.htm index.php;
# autoindex on;
}


location ~ \.(mp4|jpeg|jpg)$ {
mp4;
root /var/www/html/files;

if ($TW) {
proxy_pass http://192.168.22.32:80;
}

expires 7d;
valid_referers none blocked domain.com *.domain.com blog.domain.com
*.facebook.com *.twitter.com *.files.com *.pump.net domain.tv *.domain.tv
domainmedia.tv www.domainmedia.tv embed.domainmedia.tv;
if ($invalid_referer) {
return 403;
}
}
}

Edge config :-

proxy_ignore_headers "Set-Cookie";
proxy_cache_path /data/nginx/cache levels=1:2 keys_zone=static:100m
loader_threshold=300 loader_files=10 inactive=1d
max_size=300000m;


proxy_temp_path /data/nginx/tmp 1 2;
add_header X-Cache-Status $upstream_cache_status;
add_header Accept-Ranges bytes;
max_ranges 512;



server {

listen 80;
server_name 192.168.22.32;
root /var/www/html/files;
location ~ \.(mp4|jpeg|jpg)$ {
root /var/www/html/files;
mp4;
try_files $uri @getfrom_origin;

}


location @getfrom_origin {
proxy_pass http://002.files.com:80;
proxy_cache_valid 200 302 60m;
proxy_cache_valid any 1m;
proxy_cache static;
proxy_cache_min_uses 1;
}


Maybe i need to add some variable to get original server ip ?
