I am a total newbie to this and I don't even know if what I want to do is possible.

I have a web server that locally serves some of the files but in one case needs to pass the web requests on to another server.

For example: "https://myserver.com/weather" needs to be handled locally, but "https://myserver.com/whatever" needs to go to a different server on the network. To do this I have:

location /whatever {
proxy_pass http://10.12.45.12:1234/;
}

This works OK but the pages served by the other server have relative paths to files that are relative to THAT server. The user's browser converts the relative paths from "other_base/file_path.css" to "https://myserver.com/other_base/file_path.css".

I could add another 'location' entry to my configuration for "/other_base" but there is no guarantee that the 'other_base" name will always be the same.

What do I need to put in the Nginx configuration so that the files relative to the other server are correctly redirected (e.g. https://myserve.com/whatever/other_base/file_path.css")
