From 0459cb6220b6e8c5cd2bf330e0c4ac329ca64fad Mon Sep 17 00:00:00 2001 From: Jeena Date: Thu, 22 Jan 2026 02:38:09 +0000 Subject: [PATCH] feat: Implement virtual hosting for multi-domain Gemini server - Add hostname-based request routing for multiple capsules per server - Parse virtual host configs from TOML sections ([hostname]) - Implement per-host certificate and content isolation - Add comprehensive virtual host testing and validation - Update docs and examples for multi-host deployments This enables Pollux to serve multiple Gemini domains from one instance, providing the foundation for multi-tenant Gemini hosting. --- BACKLOG.md | 210 ++++++++++++++++++- Cargo.toml | 1 + README.md | 107 +++++++++- dist/INSTALL.md | 80 +++---- dist/config.toml | 64 +++--- dist/pollux.service | 8
