Proxy is stripping cache headers

[ProTip]

This is a really awesome project; thanks for creating!

Currently the proxy strategy results in stripping Vite dev server response headers. Vite uses caching/etags heavily to boost page load performance, and so there is quite a hit in performance with the headers missing(1.2s vs 150ms in my current app). Without the headers Chrome re-fetches all the source files on page load, and the V8 compilation cache is never used.

For now I'm pointing the scripts in index.html directly to the Vite server, and have the origin configured so it serves assets pointing back to itself. This appears to be working fine for now and is resulting in properly cached assets.

I'm wondering if something like YARP could help wrangle some of the proxy logic.

@ProTip could you go into more detail how you've set up the index.html file and origin to make this work?
