Suppose request hits my web app like this:


By using Nginx's empty_gif module, I am doing something like:

location /empty.gif { expires -1; post_action /empty_gif_post;
empty_gif; }

location = /empty_gif_post { internal; proxy_pass http://mywebapp/_track.php; }

The problem with this approach is that it won't let me retrieve GET parameters.

Any solution for this issue?

location = /empty_gif_post { internal; proxy_pass mywebapp/_track.php$is_args$args; } didn't work – infynyxx Jun 29 '10 at 16:27
That would be because you have specified it as internal. An internal location can only be accessed from within Nginx, an empty gif to the client is not internal. – Martin Fjordvald Jun 29 '10 at 20:51
