Persuading Paste HTTP server to use correct REMOTE_ADDR

Configuring reverse proxy headers was on bottom of my TODO list because I never felt it was important for my applications. Today I tried to fuddle with nginx to pass those headers but it gave me a headache.

For sake of reference and because I'm sure many others tripped on this one, here is what I figured out from mailing lists and source code (please inform me of a better, straight forward way if there is one):

Add to your deployment.ini file:

[app:main]
# ...
filter-with = proxy-headers

[filter:proxy-headers]
use = egg:PasteDeploy#prefix

Prefix middleware actually extracts proxy headers information and passes results forward. Now, nginx config:

location / {
        proxy_pass http://localhost:5000;

        proxy_set_header X_FORWARDED_SERVER $server_name;
        proxy_set_header X_FORWARDED_FOR $proxy_add_x_forwarded_for;
        proxy_set_header X_FORWARDED_HOST $proxy_host;

    }
