In HFS main window, press Alt+F6 to open "event script", inside put this:
[download]
{.set|path|{.decodeuri|%url%.}.}
{.if|{.=|{.cut||4|{.^path.}.}|/123.}|{:{.redirect|/000{.cut|5||{.^path.}.}.}:}.}
Press Ctrl+S to save it.
With this users can view /123 but when they download something they will get from /000
This is explicit, users will see the redirection in address bar.
To edit this, let's say redirect /photo to /picture:
- change /123 to /photo
- change /000 to /picture
- change 4 to 6, i.e. the length of "/photo"
- change 5 to 7, i.e. length of "/photo" +1
