Hi agentzh,

Thanks for the support and it is working :)

However, I have noticed every srcache_fetch GET /memc subrequest hits the memcached even though srcache_store skipped content-type which is not defined.

This will keep busy the memcached server and I think srcache_fetch GET subrequest should not executed if srcache_store_skip triggered first. Or am I missing something here...

map $upstream_http_content_type $no_store {
default 1;
~*html 0;
}

server {
..

location /memc {
internal;
set_unescape_uri $memc_key $arg_key;
set $memc_key $arg_key;
set $memc_exptime $arg_exptime;
memc_pass 127.0.0.1:11211;
}

location / {
srcache_response_cache_control off;
set_escape_uri $key $uri$args;
set $ttl_1d 60;
srcache_fetch GET /memc key=$key;
srcache_store PUT /memc key=$key&exptime=$ttl_1d;
srcache_store_statuses 200;
proxy_pass http://192.168.0.61:900;
srcache_store_skip $no_store;

}
..
}

Find the debug logs when firing following urls

curl -i http://192.168.0.160/index.html < served from the memcached
curl -i http://192.168.0.160/santa.jpg < not served from the memcached but the request hits the memcached
