Nginx serve a file without the filename in the adress bar

Question

Is the following behaviour possible only with nginx directives?

I want to visit the page: https://example.com/xyz When hitting enter in the adressbar I want an immediate download of the file abc.tst to be presented to the user but the adressbar should not change, it should "stay" on https://example.com/xyz and not go to https://example.com/abc.tst and the name of the downloaded file should not change to xyz.

I have experimented with various rewrite rules, or locations but can't seem to figure it out...

Answer 1

You need to use the Content-Disposition HTTP header to speficy filename different from xyz:

location = /xyz {
    alias /path/abc.tst;
    add_header Content-Disposition 'attachment; filename="abc.tst"';
}

You may also need to specify MIME type for this file, use default_type directive, for generic binary data try

default_type application/octet-stream;
