Is it possible for the post\_action directive  
[http://wiki.nginx.org/HttpCoreModule#post\_action](http://wiki.nginx.org/HttpCoreModule#post_action) to write any misses to  
the error log? How would i go about setting this up?

Thanks!

Hmm. Going out on a limb:

1. Run another Nginx vhost and define a location that proxies passes to  
it. Then check the access log of this vhost.

2. Run a script that writes a log and use the post\_action to hit that  
location with an arg that is the $request\_uri.

3. Use agentzh embedded Lua module [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/HttpLuaModule)  
and write to a log. Hitting that location with post\_action.

Just random thoughts…
