Hi,

I need to make a proxy solution. But I having some problems.

When the type [www.example.com/delivery/a/b/c](http://www.example.com/delivery/a/b/c) I need to make a proxy to  
[www.proxy.com/delivery/a/b/c/?var1=A&var2=B](http://www.proxy.com/delivery/a/b/c/?var1=A&var2=B)

So a did this configuration

location /delivery {  
subs\_filter [http://www.example.com/$uri](http://www.example.com/$uri)  
[http://www.proxy.com/$uri/?var1=A&var2=B](http://www.proxy.com/$uri/?var1=A&var2=B);  
proxy\_pass [http://www.proxy.com/$uri/?var1=A&var2=B](http://www.proxy.com/$uri/?var1=A&var2=B);  
}

Why it not working ?

Thanks and sorry for my English.

Because the HTTPSubModule replaces something on the _request body_ not  
on the configuration.

I suppose you want something like this:

server {  
server\_name [www.example.com](http://www.example.com);

location /delivery {  
proxy\_pass [http://www.proxy.com$uri/?var1=A&var2=B](http://www.proxy.com$uri/?var1=A&var2=B);  
}  
}

$uri already starts with a ‘/’.

Thanks Antonio.

Now the problem is with the images, css and others thinks.  
When the site is loaded, it try to download from [www.example.com](http://www.example.com), and  
not  
from [www.proxy.com](http://www.proxy.com).

For example, the browser try to get the [www.example.com/menu.css](http://www.example.com/menu.css), but  
the  
correct is try to download the [www.proxy.com/menu.css](http://www.proxy.com/menu.css).

How to fix it?

Thanks

Then you need to be clear on what you want.

Perhaps you just and to proxy\_pass to another host. Or if you want to  
have other stuff like images and such try:

location /delivery {

```
location ~* /delivery/[^/]*.\(?:css|js|gif|jpe?g|png)$ {
    proxy_pass http://www.proxy.com;

}

proxy_pass http://www.proxy.com$uri/?var1=A&var2=B;

```

}

I’m just guessing. We could help you more if stated more clearly  
what’s your purpose.

Yes. Add the proxy\_redirect directive:

proxy\_redirect [http://www.proxy.com/delivery/](http://www.proxy.com/delivery/) [http://www.example.com/](http://www.example.com/);

See: [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/HttpProxyModule#proxy_redirect)

I’d like to navigate on [http://www.proxy.com/delivery/.../.../.../](http://www.proxy.com/delivery/.../.../.../) using  
my  
domain [http://www.example.com/](http://www.example.com/).

So the user will navigate on [www.example.com](http://www.example.com) and always show on URL the  
’  
[www.example.com/delivery/../../](http://www.example.com/delivery/../../)..’

It’s is possible?
