Module x_forwarded 

Parsing of untrusted X-Forwarded-* header conventions.

These fields are widely deployed de facto conventions, not IETF standards. The functions here only parse raw assertions; they do not establish trust or select an effective client IP or request scheme. RFC 7239 Forwarded is the standardized alternative for forwarding information; see RFC 7239, Section 4.

Constants

X_FORWARDED_FOR

The de facto, non-IETF X-Forwarded-For field name.

The de facto, non-IETF X-Forwarded-Proto field name.
