Setting host with subpath doesn't work

[gregismotion]

Describe the bug

The service is behind an nginx reverse proxy which tries to use a subpath, like this:

location /writefreely/ {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass http://127.0.0.1:8080/
    proxy_redirect off;
}

Even if I set the

[app]
host = https://example.com/writefreely

Every link redirects to https://example.com/[actual path] instead of https://example.com/writefreely/[actual path]

Steps to reproduce (if necessary)

1. systemctl start nginx
2. systemctl start writefreely
3. Go to example.com/writefreely
4. Get greeted with the login page
5. Click on any link
6. Get routed to a bad path as described above

Expected behavior

I get redirected to https://example.com/writefreely/[actual path]

Application configuration

• Single mode or Multi-user mode? Multi-user mode
• Database? sqlite
• Open registration? no
• Federation enabled? yes

I just realised the pages are making the request from JS and they all point to /. Maybe a prefix setting could be a solution? If I can figure it out I might do a PR.

...or I might just redirect every request that WriteFreely can make with nginx.

Both of these ways are quite hacky and I don't really want to use them. I noticed that static resources actually follow the path I want, so those show up correctly. (On the login page, in the block every url is correct)
EDIT: and everything that is in the body doesn't use the correct url, even /js/webfont.js

Thanks for starting this discussion! It's true that WF was never designed to work on a path, so indeed this custom configuration is going to be an uphill battle. If you'd like to see this built in to the software, please feel free to start a discussion on our development forum so we can figure out what needs to be done and coordinate any work on this!

Was a discussion on this ever opened? I was also trying to put it under a path from my main web domain (at /blog) and had no luck when I found this issue.
