Make h5ai stop redirect to root

[biast12]

Hey i'm trying to make h5ai load up in a subfolder like this https://domain.com/archive since i want another index page like what this page got, their main page: https://valvearchive.com. and their h5ai page: https://valvearchive.com/archive, but when i'm doing it does it just open the subfolder and instantly redirect to the root, i'm not sure what i can do to fix this
