Right, but the added content can change, and this is not handled by 
nginx (well, not a real problem and taking care of the Last-Modified 
time of all included resources can be only a complication).

By the way, I have just do some test like:

         location /wsgi-read {
             add_after_body /wsgi-read/usr/local/nginx/ssi.txt;

             wsgi_pass /usr/local/nginx/nginx-read.py;

That is, using as after_body a resource that, in turn, uses after_body.

nginx does not report errors, but the page is not rendered.
