Hi,

We need to cache images while reverse proxy with the following  
settings.

```
    location /foo {
    proxy_pass http://www.example.com/foo;
    proxy_set_header X-Real-IP $remote_addr;
     if ($request_uri ~* \.(jpg|gif)$) {
    expires 60d;
    add_header Cache-Control private;
    }
    ....

```

This is working if we use it without reverse proxy. I have tried  
$upstream\_http\_request\_uri with no luck.

I have tried the following as well.

```
    location /foo/images {
    proxy_pass http://www.example.com;
    expires 60d;
    add_header Cache-Control private;
    }

```

But it matches images in /images directory not in any other directory  
within the reverse proxy domain.

Please advice how do we properly set browser cache expires while we do  
reverse proxy.

Thanks in advance
