# Reverse Proxy Misconfigurations

## 1. Nginx alias traversal
Nginx `alias` directive (vs `root`) is dangerous when URL pattern is
prefix-based but alias is a directory:
```nginx
location /static {
    alias /var/www/static/;       # trailing slash CRITICAL
}
# But buggy:
location /static {
    alias /var/www/static;        # NO trailing slash → path traversal possible
}
```
