This message starts a httpbis WG Call for Adoption of: draft-rosomakho-httpbis-outdated-proxy-config-01 This Working Group Call for Adoption ends on 2026-02-03 Abstract: This document defines a lightweight mechanism that allows explicit HTTP proxies to inform clients when their proxy configuration, such as a Proxy Auto-Configuration (PAC) file or Provisioning Domain (PvD) proxy configuration, is outdated. Clients signal to the proxy the configuration URL and the timestamp of when it was last fetched. In response, the proxy may indicate that a newer version of the configuration is available. This enables clients to refresh their configuration without relying on frequent polling or short expiration intervals. The mechanism is designed to be compatible with existing proxy deployment models and supports both PAC-based and PvD-based configurations. Please reply to this message and indicate whether or not you support adoption of this Internet-Draft by the httpbis WG. Comments to explain your preference are greatly appreciated.
