here is my conf
http{
...
proxy_buffer_size 4k;
proxy_buffers 1024 4k;
proxy_temp_path /data/nginx/proxy_temp ;
proxy_cache_path /data/nginx/proxy_cache levels=1:2
keys_zone=cache1:1000m;
...
server{
...
location ~* \.(ico|css|js|gif|jp?g|png|xsl)$ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://61.129.66.75:80;
proxy_cache_key shtatic$request_uri;
proxy_cache cache1;
break;
}
....
}
the initiall request when there isn't and cache, everything is ok. the
following request to same url will wait until timeout.
this is the debug log around the second request:
