SSE vs. proxy

[bfallik-invaluable]

I'm building a web app and using air's proxy capabilities for reload. SSE in my app only works when I connect to the app port. When I connect to the proxy port, it seems like the SSE request makes it to my application but the browser doesn't see the server's response.

I understand the air proxy is implemented using SSE and that seems to be working as expected. That is, when using the proxy port the browser reloads when air restarts the app.

I'm not sure what's causing this problem or even how to debug this further. Would appreciate any suggestions!
