Hi,

I’m using nginx 1.0.0 and I wonder if there is any way of telling  
“X-Accel-Redirect” to keep the “Etag” header.  
The rest of the headers from upstream are kept when I set  
“X-Accel-Redirect” but “Etag” seems to be removed.

Regards.

There are several headers which are kept on X-Accel-Redirect:

“Content-Type”, “Set-Cookie”, “Content-Disposition”,  
“Cache-Control”, “Expires”, “Accept-Ranges”

Others aren’t kept by default. If you want to keep them, try  
something like

```
add_header Etag $upstream_http_etag;

```

in the location your X-Accel-Redirect points to.

(if you proxy\_pass to another server after X-Accel-Redirect, you  
will have to save $upstream\_http\_etag to temporary variable via set  
directive, but this is another story)
