hi,

I want to pass the following header to the backend server:

```
name: X-Original-URL
value: $scheme://$host$request_uri

```

but the concatenation of the values for the value above do not seem to  
work.

how can I do that?

thanks,

–

proxy\_set\_header X-Original-URL $scheme://$host$request\_uri;

works for me.
