 ============
 * On certain systems, enabling aio and/or sendfile may stop [srcache_store](#srcache_store) from working. You can disable them in the locations configured by [srcache_store](#srcache_store).
-* The [srcache_store](#srcache_store) directive can not be used to capture the responses generated by [echo-nginx-module](http://github.com/openresty/echo-nginx-module)'s subrequest directivees like [echo_subrequest_async](http://github.com/openresty/echo-nginx-module#echo_subrequest_async) and [echo_location](http://github.com/openresty/echo-nginx-module#echo_location).

You are recommended to use HttpLuaModule to initiate and capture subrequests, which should work with [srcache_store](#srcache_store).
