The line 182 in your error.log snippet gives you the answer:

2012/03/08 10:49:10 [debug] 20521#0: *11 srcache_store skipped due to
response header Cache-Control

That is, the response from your backend server explicitly prohibits
caching via the Cache-Control response header. And the line 191 in
your error.log snippet confirms this:

Cache-Control: no-cache

If you want to enforce caching in this very case, just turn on the
srcache_store_no_cache config directive, like

    srcache_store_no_cache on;

See http://wiki.nginx.org/HttpSRCacheModule#srcache_store_no_cache for
more details.

Or turn off the srcache_response_cache_control config directive to
make ngx_srcache ignore the Cache-Control response header altogether:

    srcache_response_cache_control off;

See http://wiki.nginx.org/HttpSRCacheModule#srcache_response_cache_control
for more details.
