nginx-esi's Issues

ESI Include Ordering and ESI Remote Fetch issues

Using: taf2-nginx-esi-0fe5af2
nginx_0.7.65

cat /etc/nginx/nginx.conf

user www-data;
worker_processes 1;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
debug_connection 192.168.24.68;
}

http {
include /etc/nginx/mime.types;

access_log  /var/log/nginx/access.log;

server {
listen 192.168.24.100:83;
server_name 192.168.24.100;
location / {
esi on;
root /var/www;
}
}
}

cat index.html

(index.html) This is the base document

results in the html emitted:

(esi/included.html) this is the server side include

(esi.html) this is a test ESI document

(index.html) This is the base document

So, it appears that the substitution is done but the content pasted to the top of the response header rather than the interior. You can see the empty lines where the <esi:include was removed.

Also, when using a URL rather than a local path, i.e. <esi:include src="http://192.168.24.100:83/esi.html" />

/usr/local/nginx/html is added prior to the url during the subrequest which causes it to fail.
