Possibility for reverse proxy adoption / Change base url

[mr-honest]

Hi.

Would it be too much work for you to allow for reverse proxy, so I can use subfolder directive on nginx?

So instead of http://domain.com:8000, I can access by http://domain.com/speedtest

I did try different rewrite rules in nginx, and the closest i got was this:

location /speedtest {
        rewrite ^/speedtest(.*)$ $1 break;
        proxy_pass http://speedtest:8000;
    }

However this will not load the svg graphics.

I think that all you need to change is add a trailing slash to your proxy_pass directive:

location /speedtest {
  rewrite ^/speedtest(.*)$ $1 break;
  proxy_pass http://speedtest:8000/;
}

I'm not sure though, that's off the top of my head. There is definitely a trick to do this in nginx without needing to change speedtest-plotter in any way.

Hi, I did also try your method, and still the vector graphic would not load. I have tried for many hours, and finally it seemed the solution was to change the backend, to allow for url rebase.

Indeed, that's because the form action and the SVG in the page were using a leading slash. Removing that / changing it to . enabled a reverse proxy with a subdirectory location. See diff in b881e48383419c0b80beece7b0acd91dc30da11d.

I tested this locally with an nginx configuration that did not even need a rewrite directive:

location /speedtest/ { # trailing slash here seems to be important, too
  proxy_pass http://speedtest:8000/;
}

edit: you'll need to wait until the CI build is finished and re-pull the image.
