Hi,

I’m using proxy\_pass in front of CouchDB, which has file paths which  
contain some URL encoded characters (e.g.  
[http://couch:5984/images[b]%2F[/b]logo.gif](http://couch:5984/images%5Bb%5D%2F%5B/b%5Dlogo.gif))

I am trying to to replace some characters in requests to nginx with the  
URL-encoded equivalent:

[http://localhost/images/logo.gif](http://localhost/images/logo.gif) →   
[http://couch:5984/images[b]%2F[/b]logo.gif](http://couch:5984/images%5Bb%5D%2F%5B/b%5Dlogo.gif)

My attempt was this:

```auto
rewrite ^/images/(.*)$ /images%2F$1 break;

location ^~ /images {
       proxy_pass http://couch:5984;
}
```

However, it looks like proxy\_pass is double-encoding the % character,  
which results in the following CouchDB request:

‘GET’ /images%252Flogo.gif

How might I do the following rewrite?:

[http://localhost/images/logo.gif](http://localhost/images/logo.gif) → [http://couch:5984/images%2Flogo.gif](http://couch:5984/images%2Flogo.gif)

Thanks

Anyone have an idea on this?
