Streamlit Host in IIS server

Welcome to the Streamlit community, and thanks for sharing such a thorough step-by-step guide! Your instructions for deploying Streamlit on Windows Server with IIS as a reverse proxy (including full WebSocket support) are well-aligned with best practices and community recommendations. The key steps—installing URL Rewrite and ARR, enabling proxy and WebSocket support, running Streamlit as a Windows service (NSSM), configuring Streamlit for headless/proxy use, setting up IIS site bindings, and writing the correct web.config rules—are all essential for a robust deployment.
