The proxy does ngx_escape_uri() if URI was rewritten.  It has to, 
as unencoded URI can't be used in a HTTP request.  Take a look at 
the ngx_http_proxy_create_request() function as previously 
suggested.

As long as there were encoded slashes, the encoding of these 
slashes will be lost if URI was rewritten.  This is the expected 
behaviour.
