+# Force HTTPS during development
+
+## Summary
+
+This sample demonstrates how to use Dev Proxy to automatically rewrite HTTP requests to HTTPS during development. This helps match production security locally and test against HTTPS without certificate hassles.
+
+## Compatibility
+
+![Dev Proxy v2.0.0](https://aka.ms/devproxy/badge/v2.0.0)
+
+## Contributors
+
+* [Waldek Mastykarz](https://github.com/waldekmastykarz)
+
+## Version history
+
+Version|Date|Comments
+-------|----|--------
+1.0|January 10, 2026|Initial release
+
+## Minimal path to awesome
+
+* Clone this repository (or [download this solution as a .ZIP file](https://pnp.github.io/download-partial/?url=https://github.com/pnp/proxy-samples/tree/main/samples/http-to-https-redirect) then unzip it)
+* Start Dev Proxy: `devproxy`
+* Test the rewrite by making HTTP requests that will be automatically redirected to HTTPS:
+  ```bash
+  # This HTTP request will be rewritten to HTTPS
+  curl -ikx http://127.0.0.1:8000 http://jsonplaceholder.typicode.com/posts/1
+
+  # Dev Proxy will intercept the request and change it to:
+  # https://jsonplaceholder.typicode.com/posts/1
+  ```
+
+## Features
+
+This sample provides a Dev Proxy configuration that rewrites HTTP requests to HTTPS:
+
+**Rewrite Rules:**
+* HTTP to HTTPS - Rewrites all `http://` URLs to `https://`
+
+**Key Benefits:**
+* **Match production security locally** - Ensure your development environment uses HTTPS just like production
+* **Test against HTTPS without certificate hassles** - Dev Proxy handles the protocol rewriting transparently
+* **Easy to customize** - Add more rewrite rules in `.devproxy/rewrites.json` for additional URL transformations
+
+**Additional Rewrite Patterns:**
+You can extend the `.devproxy/rewrites.json` file with additional patterns such as:
+* Change API versions (v1 to v2)
+* Redirect staging to production URLs
+* Add/modify query parameters
+
+Using this sample you can use the Dev Proxy to:
+
+* Automatically force HTTPS for all HTTP requests during development
+* Test HTTPS behavior without modifying your application code
+* Ensure consistency between development and production environments

+# Screenshot Placeholder
+
+A screenshot demonstrating Dev Proxy rewriting HTTP requests to HTTPS needs to be added to this folder.
+
+The screenshot should:
+- Be named `screenshot.png`
+- Have a resolution of 1920x1080 (preferred)
+- Show the terminal output of Dev Proxy intercepting an HTTP request and rewriting it to HTTPS
