NginX problem with Reverse Proxy'ing

Hi, I have a little problem that’s driving me crazy since 4 days. I’m
trying
to create a server with NginX (0.8.35) serving static content (PDF files
mainly) as frontend and Apache2 as backend processing the PHP files,
actually I’m working only with basic PHP (phpinfo()) files for testing
purposes (this isn’t my production machine, only a
pre-production-kind-machine. Apache is running in 127.0.0.1:8080

When I’m trying to proxy the PHP to Apache is issuing a 301 Redirection
(i
tested it with cURL from another host, and giving a network error in IE8
and
Chrome.
Here I include the config files loaded in 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;
# multi_accept on;
}

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

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

sendfile        on;
#tcp_nopush     on;

#keepalive_timeout  0;
keepalive_timeout  65;
tcp_nodelay        on;

gzip  on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-available/*;

}

sites-available/www

server {
listen 80 default;
server_name blog.foo.com;

access_log /var/log/nginx/foo.access.log;
error_log /var/log/nginx/foo.error.log;

location / {
root /var/www2;
index index.php;
proxy_pass http://127.0.0.1:8080;
include /etc/nginx/conf.d/proxy.conf;
}
}

conf.d/proxy.conf

proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 16k;
proxy_buffers 32 16k;
proxy_busy_buffers_size 64k;

Now the -i from cURL in blog.foo.com/index.php

So, your php code returns 301 redirect. Probably it’s a good idea
to look into your php code?..
