## Overview

Stockport Web App is a business-ID-aware ASP.NET public website that serves council content supplied by a separate ContentAPI. Its principal request path is browser request through business selection and a content controller, then repository/API retrieval and a rendered response. The tree also shows distinct news, events, directory, payment, contact and search capabilities, plus content transformation and shared web safeguards. Source excerpts confirm the news/events retrieval pattern and repository HTTP calls; other feature wiring is represented by its modules, not inferred. The README documents the ContentAPI dependency and supported business IDs.

Main entry points: [`src/StockportWebapp/Controllers/EventsController.cs`](https://github.com/smbc-digital/iag-webapp/blob/main/src/StockportWebapp/Controllers/EventsController.cs) (Events and calendar), [`src/StockportWebapp/Controllers/NewsController.cs`](https://github.com/smbc-digital/iag-webapp/blob/main/src/StockportWebapp/Controllers/NewsController.cs) (News and RSS), [`src/StockportWebapp/Repositories/Repository.cs`](https://github.com/smbc-digital/iag-webapp/blob/main/src/StockportWebapp/Repositories/Repository.cs) (Content repository), [`src/StockportWebapp/Controllers`](https://github.com/smbc-digital/iag-webapp/tree/main/src/StockportWebapp/Controllers) (Page controllers)
