X-Accel-Redirect to keep Etag from upstream?

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)

Thanks, it worked.

Regards.
