# =============================================================================
# 企微智能IT支持服务台 — Nginx 配置（公司内网服务器版）
# =============================================================================
# 适用场景：独立域名 itsupport.servyou.com.cn，公司内网 DNS 解析
# 与 NAS 版的区别：
#   1. 移除 Cloudflare 相关头（X-Forwarded-Proto https 等）
#   2. server_name 改为正式域名
#   3. 真实 IP 直接从 $remote_addr 获取（无 CF 代理层）
#   4. 预留 HTTPS 配置注释（如公司有统一 SSL 终端）
