How do I add text to a response from a remote URL in NGINX?

Thanks for the reply. :-)

I have added a location as follows:

location ~/src/(.*) {
        proxy_pass http://externalserver.com;
}

It works when the entire URL is loaded in a browser. However, in the
"autoindex" page, "Object Moved
This document may be found _here_" show up before and after the files list.
