Non-Root Web Path

When installing FastCGI applications in a non-root path (e.g., http://example.com/myapp/), some applications expect PATH_INFO and SCRIPT_NAME parameters similar to Apache.

---

Apache Equivalent

FastCgiExternalServer /var/www/myapp -socket /path/to/myapp.sock

---

NGINX Configuration

location ~ /myapp(?<path_info>/.*|$) {
    fastcgi_pass unix:/path/to/myapp.sock;
    include /etc/nginx/fastcgi_params;

    fastcgi_param PATH_INFO $path_info;
    fastcgi_param SCRIPT_NAME "/myapp";
}

---

How It Works

Request	PATH_INFO	SCRIPT_NAME
/myapp/	/	/myapp
/myapp/page	/page	/myapp
/myapp/api/users	/api/users	/myapp

Compatible Applications

This configuration works with:

• Mercurial (hgweb.cgi)
• Trac
• Zope (via FastCGI)
• Many Python WSGI applications
