Hello I’m using nginx as reverse proxy for some domain … my
configuration
for domain looks like that :

server
{
listen 80;
server_name www.mydomain.com mydomain.com;
index index.html index.htm index.php default.html
default.htm;
location / {
proxy_buffering off;
proxy_max_temp_file_size 0;
proxy_pass http://www.domainresultget.com;
}}

response header from this domain “www.domainresultget.com” looks like
that

HTTP/1.1 200 OK
CF-RAY: 11d864fce3900a9c-PRG
Connection: keep-alive
Content-Disposition: attachment; filename=“filename_title_download.exe”
Content-Length: 351744
Content-Type: application/x-msdownload
Date: Sat, 19 Apr 2014 10:24:48 GMT
Server: nginx
X-Powered-By: PHP/5.3.3

The Content-Disposition header value from upstream response is
available as $upstream_http_content_disposition variable (see
http://nginx.org/r/$upstream_http_). The map module can be used
to extract part of the value, see http://nginx.org/r/map.

I have tryeid to do something like this but it seems that variable
$upstream_http_content_disposition is empty… when I want to redirect to
different url…

proxy_pass http://www.domainresultget.com;
set $x $upstream_http_content_disposition;
return 301 http://domaintest.com/test.php?x=$x;

variable $x is empty…

This is not going work, as “return 301” will happen before the
proxy_pass. See here for basic explanation on how rewrite module
works:

http://nginx.org/en/docs/http/ngx_http_rewrite_module.html.

It looks like you want nginx to do a request to upstream server,
and then return a completely different response to a client. In
case of 200 responses, this is something that can be done, e.g.,
by using auth request module, see here:

http://nginx.org/en/docs/http/ngx_http_auth_request_module.html

It might also be a good idea to change your backends to actually
return responses you want to be returned to clients instead of
trying to change them with nginx configs.
