My nginx proxy configuration:

```
    location / {
        proxy_pass http://site.external.com/;
        proxy_redirect http://site.external.com 

```

[http://site.local.my](http://site.local.my);  
proxy\_set\_header Accept-Encoding “”;  
sub\_filter [http://site.external.com](http://site.external.com) [https://site.local.my](https://site.local.my);  
sub\_filter\_types text/xml text/css text/javascript;  
sub\_filter\_once off;  
}  
Every thing would be great but [site.external.com](http://site.external.com) sets cookie with  
domain .external.com and browser doesn’t accept it. So i would like to  
filter the header of the response, or inject a cookie (add\_header  
Set-Cookie "JSESSIONID=…) based on existing Set-Cookie http  
response.

Can any one suggest a configuration, module, link … whatever ?

Best regards.
