I am working to get Calibre reverse-proxied by NGINX webserver. The basic NGINX setup as presented in the documentation works well (note that NGINX is hosted on 10.192.0.26 and calibre-server is running on a different computer, 10.192.0.2):

server {
        listen 80 default_server;
        server_name localhost 10.192.0.26;
        proxy_set_header X-Forwarded-For $remote_addr;
        location /calibre/ {
                proxy_buffering off;
                proxy_pass http://10.192.0.2:8080$request_uri;
        }
        location /calibre {
                rewrite /calibre /calibre/ permanent;
        }
}

And this is how I'm starting the calibre-server on 10.192.0.2:

calibre-server --url-prefix /calibre --num-per-page=999 --port 8080

The above works fine. But I want to tweak something. And it's an NGINX thing, not a Calibre thing. However, I figured that some folks here have fronted Calibre with NGINX and may know NGINX.

Currently, if I go to http://10.192.0.26/calibre (that's the NGINX server URL) then it jumps to http://10.192.0.2:8080/calibre (that's the calibre-server URL). Great. But what I want is if the user enters this:

http://10.192.0.26/calibre

... then NGINX translates that to:

http://10.192.0.2:8080/calibre/#library_id=Calibre&panel=book_list&sort=author_sort.asc,series.asc&vl=Novels

... so that the user does not hit the Calibre default screen where they then have to manually choose a library, a virtual library, and a sort order. I want to automatically give them my preferred view (library, vl, sort). Then later they can change all this is the want, but they start out with MY defaults, not Calibres.

I know I could just have them bookmark the full URL (including fragment) that I am proposing to rewrite above. But this is something I think I should be able to do automatically in NGINX. But being new to NGINX, I don't know how.

In a nutshell:

If user hits NGINX with generic (no fragment at the end of the URI) http://10.192.0.26/calibre, then rewrite to add the fragment that defines my preferred library/vl/sort.

But if user hits NGINX with a Calibre URI with a fragment on the end, then leave it as-is and don't try to rewrite.

After getting this rewrite fixed, next up I will use my DDNS name, httpS with LetsEncrypt cert, and client cert authentication. One step at a time though. I'm just working on the rewrite and basic reverse proxy stuff first.
