Apache: add static file under root of mounted WSGI appilication

gistfile1.txt

It's possible with Alias directive which is used like this

Alias /google_485135.html /usr/egan/google_485135.html

You can get 403 when serving of the file is working
to solve it you need to configure access to file on Apache level.

Alias /google_485135.html /usr/egan/google_485135.html
<Directory /usr/egan>
    Require all granted
</Directory>

OR just use filesystem location with already configured permissions
for example ../static which is almost always is configured properly.

Also check that Apache has access to file in filesystem permissions,
if it's no - there will be the same 403 but the reason will be exactly filesystem permissions
