404 on ctrl-shift-r refresh of non-home page in starter kit

[eatonphil]

Description

Doing a hard-refresh of a non-home page view causes a 404 in the starter kit.

Live Demo

None.

Steps to Reproduce

1. Create a new polymer-3-start-kit through polymer init
2. Build the project with yarn build
3. Start a server and navigate to the home page (cd build/es6-bundled && python3 -m http.server 9091 && open localhost:9091)
4. Go to view 3 (http://localhost:9091/view3)
5. Hard-refresh with ctrl-shift-r

Expected Results

A hard-refresh should load the page correctly. A hard-refresh on the home page (http://localhost:9091) loads successfully.

Actual Results

A hard-refresh always causes the non-home page view to 404. Even after a hard-refresh if you soft refresh the non-home page loads correctly.

This is expected if using base Python HTTP server.

You need something to redirect requests to index.html. You might want to check out: https://www.npmjs.com/package/es-dev-server

That makes sense, thanks. The cached behavior threw me off.
