What to expect from configuring "pretty URLs"

Hi

I don’t know what exactly to expect from setting up “pretty URLs”.

I have done configuration as suggested in “https://docs.nextcloud.com/server/18/admin_manual/installation/source_installation.html#pretty-urls

When reaching the instance by “hostname.sld.tld” browsers address field shows “https://hostname.sld.tld/login” and after logging in “https://hostname.sld.tld/apps/files/?dir=/&fileid=6”. I’m not shure if this is as expected or if i’m missing something.

Some advice would be nice.
thx
