Nginx proxy_redirect: Change response-header Location and Refresh in the response of the server

How do I replace upstream "Location: http://server1.cyberciti.biz:8080/app/" http/301 response-header with "Location: http://www.cyberciti.biz/app/" in the response of the proxied server using nginx?

Nginx provides proxy_redirect directive which can be used in http, server, or location context. The syntax is:

 
proxy_redirect redirect replacement
 

In this example, the proxied server (upstream Apache or Lighttpd) returned line Location: http://server1.cyberciti.biz:8080/app/. The following directive in nginx.conf:

 
proxy_redirect http://server1.cyberciti.biz:8080/app/ http://www.cyberciti.biz/app/;
 

will rewrite this line in the form Location: http://www.cyberciti.biz/app/. Save and close the file. Reload the nginx server
# service nginx reload
OR
# /usr/local/nginx/sbin/nginx -s reload
You can verify this with the curl command:
$ curl -I http://server1.cyberciti.biz:8080/app/
OR
$ curl http://server1.cyberciti.biz/app/

In the replace line, it is possible to use variables as follows:

 
proxy_redirect   http://server1.cyberciti.biz:8070/    http://$host:$server_port/;
 

The parameter off forbids all proxy_redirect directives:

 
proxy_redirect off;

Hi,
Thanks for ALL your articles, about nginx and [lu]nix ;-)
I’ve a question about nginx. And I hope you can answer it ;-)
We do reverse proxy to access from internet some documentation filtering by ip address. These documentations are hosted on commercials portals.
For 1 base we are often redirect between 2 or 3 (sometimes 6) servers.
And we have access to more than 50 bases !
Do you know if with nginx it’s possible to do proxy_pass (and proxy_redirect) to these server one 1 virtual name ?
I try it with different location for each server but it’s doesn’t work.

Thanks in advance for your help. You can contact me at ceooph@gmail.com
And continue your blog ! When I search documentation about linux and I find an article on your site, I know that I’ll have to response ;-)
