CheerpJ works with Node's http-server but not with Python's http.server

kolovos commented 9 months ago

To reproduce this issue:

Clone https://github.com/kolovos/cheerpj-epsilon
Run mvn package to produce the JAR file
Run npx http-server from the root of the repo
Open http://localhost:8080
After a few seconds, the page reads "Hello from Epsilon" as expected
Shut down http-server
Now run Python's http.server also from the root of the repo using python3 -m http.server 8080
Open http://localhost:8080
The expected text ("Hello from Epsilon") is not shown on the page and the following error is produced in the browser's console instead (both in Firefox and in Chrome):

Does this Web server support HTTP byte ranges? It is a basic HTTP feature and it's required for CheerpJ

Many thanks for the quick response. No, it doesn't seem to support range requests https://github.com/python/cpython/issues/86809
