base
- the
determinationportion is appended tobaseportion - last way =
base+determination
alias
- the
determinationportion is changed by thealiasportion - last way =
alias
To exemplify:
Fto’s opportunity we person the config

This is due to the fact that the determination portion is appended to the way specified successful the base. Therefore, with base, the accurate manner is
determination /static/ { base /var/www/app/; autoindex disconnected; }
Connected the another manus, with alias, the determination portion will get dropped. Truthful for the config
determination /static/ { alias /var/www/app/static/; autoindex disconnected; ↑ } | wage attraction to this trailing slash
the last way volition appropriately beryllium shaped arsenic
